hey guys i was trying to troubleshoot my pc and finally decide to test nvidia maths/mods but the test starts automatically unlike the youtube video ( channel name "learn electronics repair" ) in which the guy choose the card and test himself. my question is that should i believe test result?. does i messed up something when i was installing software? link of my test guy channel video thanks

hey guys i was trying to troubleshoot my pc and finally decide to test nvidia maths/mods but the test starts automatically unlike the youtube video ( channel name "learn electronics repair" ) in which the guy choose the card and test himself. my question is that should i believe test result? does i messed up something when i was installing software? i just want to know is my gpu is ok or not. my gpu is in warranty but i do not want to send it for rma on the basis of wrong report because rma process in my country can take 3-4 months link of my test guy channel video thanks

Hey guys! I recently exchanged a few comments with @AlexTheGreatish in the comment section on the floatplane video about the 10.000RPM fan. We talked about modeling CPU coolers, and neither of us was quite sure how to predict heatpipes properly. In the end I found citations mentioning that they behave roughly like conductors and are in the range of 1.5-5 W/K for small heatpipes like in the typical tower cooler. Now I want to collect data on it, especially the accuracy. I did the maths and the experiment for my CPU and cooler a few times and find that my cooler reaches about 85% of its theoretical limit. So now I have made an excel table that does all the maths for you, als also gives a predicted temp, so that you can use it to estimate whether or not a cooler is enough for a given CPU. I'd be extremely greatful, if you could fill in the cells with grey background for your coolers and cpus (AI suite gives CPU power draw, fan speed and temp in one place) and post the performance in % here in the thread, ideally for idle and load. Mine are between 80-85% for load and 90-92% for idle. Here is a google doc you can copy to your drive EDIT: -replaced excel download with google sheets link -added thermal compound

U = K- P This is the original expression and the task was to rearrange to make D the subject. 3D-Y -K (U-K)= -P 3D-Y *(3D-Y) (U-K)(3D-Y)=-P 3DU-3DK-UY+KY=-P this is as far as I have been able to get so far. If its obvious to you what to do next would you mind explaining rather that commenting the answer with some hilarious quip like "git gud".

u^2 = n^2 + 2n How would I rearrange this for n? Any help is greatly appreciated!

Soo I have solved a trigonometry question on youtube to test myself and find an awnser, then I watched how the teacher solved it and it was slightly diffrent than mine so he got the awnser: (3 + sqrt(3)) / 6 Where I got (1 + sqrt(3)) / (2 . sqrt(3)) Sooo which one is valid in an exam and which one is the you know, last version, most simplified version. How can I simplify it? And thanks

Hi, I am currently writing notes on paper then taking photos and sendiong them to my laptop. I use typing for most but for doing equations it is quite challenging! What is the best (not too expensive) tablet type thing, ie ipad or surface, that i can write notes on in order to do this stuff. Has anyone had experience in the past with this? Thanks

Hey all, I am having some trouble with a piece of homework for Year 11 Maths. I was just wondering how you would factorise 4x3 - 9x2 + 6x - 8. I put it into Wolfram Alpha and it gave me (x-2)(4x2 - x + 4), but I don't know how to get there by myself. It is probably something really simple that I have just overlooked, but any help would be much appreciated! Thanks

I'm no math genius, not even close but I think my passion for this area can outweigh the general stereotype. I honestly know/understand content I'm taught but when exams come my way - I mess up while trying to find the solutions; on paper I'm terrible. (If it matters what I wanna do in IT, I wanna do Business Management or Project Manager/Leader - the leadership rolls appeal to me more) What do you think, is this general notion true, or false?

Dear loyal subjects, My partner isn't very interested in videogames. She doesn't go in for shooters or RPGs or builders etc. She doesn't like violence, and she is easily bored by many of the concepts found in video games. She even got annoyed and stopped playing Portal because she got irritated by GLaDOS' "Stupid voice". There is one genre she does enjoy though and that is puzzle games. (That's why I suggested Portal). But every single puzzle game she has tried she says is easy, or not very mentally challenging where the only difficulty the developer has slapped on was a time limit. Strangely the only videogame that has really captivated was 'Zork', she didn't mind the black screen and the white text. She enjoyed the difficulty and the reliance on visualising the scene and the problem in her head. (Something you do with maths a lot) She is a Chemistry and Maths student at a very top university and loves her subjects, she wants to play video games with me because she loves me and I want to include her in this amazing hobby we all share. Guys and girls, can you help me? I need to find for her a mentally challenging game, that hopefully requires you to use complicated maths, logic or deduction or anything that is more challenging than sliding blocks and solving mazes, I want to show her that modern video games aren't all about killing and shooting. Thank you

Hey guys, so as any UK school kid in 1st or 2nd year in high school (year 7 and 8?) who enjoys maths may know, the UKMT challenge is happening this week and so I was doing some passp paper and hit a few questions, so with a family who's pretty poor at maths, I turned to THE INTERNET! So I am struggling with question 16, 21 and 25. The rest I have done. For question 16 - well I don't even know where too start as I don't fully understand the question so if any one could explain it to me or show working as how a they got it, would be incredibly helpful. 21 has also stumped me - I think it has something to do with simultaneous equations, but when I tried that method suggested here: http://www.bbc.co.uk/schools/gcsebitesize/maths/algebra/simultaneoushirev1.shtml I got varying answer when tried in different equations, straight up making no sense. And on question 25 I again believe it to have something to do with simultaneous equations and not only have we not yet been taught it in school (which I find personally not an excuse) but I was struggling to carry out the method suggested by the BBC when it resulted to 3 equations at once. However I did managed to gather the equations needed to solve question 25 (or at least I think I did) which I will attach a photo of. All questions are located below! If anyone could help by showing me some working or how they did them, or in the case of 16, simply explaining what it wants me to do! Thanks again, Xvantok

I hope this is the right forum btw, I think this counts as software... Lightweight Java Prime Finder What is it? This is a multithreaded program I recently created in Java that can be used to find huge prime numbers. It has a strong emphasis on ease of use and performance. It is multithreaded and heavily optimised so it runs extremely quickly and can find new prime numbers with thousands of digits in just a few minutes. How to use? How to use it is relatively simple. It accepts a "starting number" in the form of x^y+c, then it checks every number greater than the starting number using a combination of the Fermat Test for Primality and Trial Division to see if it is prime. You can follow the onscreen instructions and it will give recommended settings based on your machine! I recommend starting from a 'small' number, such as 3^3000 just to see if everything is working alright for you. The exciting thing is that this can be used to find primes that haven't been discovered before! For example: the largest prime I have found using this application is: 12^15000 + 9367 (16188 digits). Which as far as I have researched has never been discovered or computed by anyone else! It took my computer (Quad Core i5 @ 3.10 GHz) running at 100% CPU for 36 hours non-stop to scan through all the numbers (starting from 12^15000) and to validate that this is a prime. I have linked the full number file below. 12^15000+9367.txt 15.81KB 0 downloads Download Link to github. (If you have any feedback on my coding please do mention it, I'm entirely self-taught!). TODO: · Replace that huge SWITCH statement that is the main menu with smaller methods. · Stop recursively calling the main menu again and again as a restart (can cause a stackoverflowerror). · Have a standard method to take input from the user rather than a bunch of smaller ones. That’s all, if anyone does find a new prime number be sure to tell me!

With the incoming release of Windows 10 and DirectX 12 we've seen some of the crazy (yet amazing) changes DirectX 12 will bring for Gaming Enthusiasts One of the biggest and best changes (in my opinion) is not just that you can cross platform your GPUs from nVidia and AMD but no longer will you have your cards VRAM removed when you go SLI or Crossfire. So in previous generations, if you had 2 780's, which are 3gb's Each, instead of the VRAM adding up to 6gb's you only had the first cards 3gb's. Now with DX12, the 2nd graphics cars is "Bound together" with the original, allowing your computer to act like they are one being, like the first card is a symbiotic entity of some kind. So for those who struggle "wit da mathz", having 2 x 780's would then give you 6gb's of VRAM! So what does this mean for the future of graphics cards? Well, with 4k Screens becoming cheaper by the day (As we are so often told by our reviewing overlords) and the fact they basically need 4gb of VRAM to even attempt running these resolutions at a decent standard we could now see users going overhaul on cheaper graphics cards to run 4k AAA Title games. Not only this, but if I read this correctly, if you had a 970 and its 3.5 DEDICATED VRAM ( I caps'ed dedicated because you know why) and a 960, in theory, the 2gb of VRAM from the 590 should apply to the 970, giving it 5.5gb of VRAM. What are your opinions on this change? Are you also drooling from the face hole? One thing to note though, like many games, it is up to developers to allow these multi-gpu combinations to be utilized. Many games still either have trouble or don't properly use SLI/Crossfire properly be it through choice or what not, so will they be allowing this to be used in their games? We can only hope. I'd love to hear what you've hear or please feel free to correct me if I'm wrong. But this all sounds rather tickety boo if you ask me.

a+b=10 ab=16 find the value of a^2+ab+b^2 USING IDENTITIES btw ik this place is for CPUs, CPUs are for numbers,numbers are for math(plz dont flame) EDIT: well looks like i read the sum wrong , so i actually knew the answer all along.

Inspired by LawrenceBarnes2013 post for help with derivatives, post all those nasty maths problems that give destroy your precious sleep cycle. Algebra, geometry, calculus, sequences and series, not a problem; our friendly community is here to help. Let's work together and make this the best thread for beating that top guy (or gal) in class with homework @LukaP @TheHolyCawCaw Don't be afraid to post physics here too!

Winning maths test was never been easier before MicroBlink (a text recognition technology company) Launched PhotoMath , An Application which takes snapshot of your math equation from a tex book or written down on a peice of paper (Turns out it doesn't work ) & solves it for you.. The application uses your smartphone's camera to scan math equations and not only solve them, but show the steps involved , Originally, it's meant to save you time flipping through a textbook to check answers when you're doing homework or cramming for a test. The Application is available on iOS and Windows Phone & Android version is delayed till early 2015 Best of all , it's free (for now) PS: You're welcome.. B) Bonus: Head over to https://photomath.net/ to download for iOS or Windows Phone. Android users have to wait till 2015 (take that samsung fanboys) Post your thoughts/comments & rants down below

So I have a few questions I need help with. This one (probs easy, just don't know it off the top of my head): Find the Area And also can someone check if my working is correct and I have the correct answer in the end (my diagram isn't great, mainly for the pro-numerals). Find the radius of the smaller circle, if the radius of the bigger circle is 1. Working: OC=√2r OA=1 OC+CA=1 √2r+r=1 r(√2+1)=1 r=1/1+√2 r=√2-1 which is around about equal to 0.414213

Need to do this and don't have a clue so if anyone would be kind enough to help me, it would me much appreciated.

My maths homeworks is to make a powerpoint on any area of maths I want, for example, someone last year made on on zombie killing. I am 17 and doing my AS levels so this powerpoint should be in depth but is also meant to be a bit of fun. Any suggestions on areas of maths I could make my powerpoint on? Of course I am interested in computers so something computer bases would interest. Any help is appreciated. David

Hey there! I'm trying to create a little program for my calculator (Casio Prizm) to solve Linear Diophantine equations of the form ax+by=c. My progress so far has been to code in a way to check if the equation has a solution (by the means of GCD). What I've done, more specifically, is check if the fractional part of the division between C and the GCD(A,B ) is different from 0. If it is, then it has no solution. If it isn't, well, it has. I've coded something like this: If (Frac (C/GCD(A,B )≠0) Then "No Solution" Else IfEnd That's how I have that set up. Now, I need to do the Else part. What I need to do is Divide "A" between "B", store its quotient for later use, and then divide B by the Reminder (call it R1) of A divided B. Then, I would store the quotient of B divided R1 and use its reminder (call it R2) to divide R1, and store its quotient, etc, etc, etc. I have access to the function "Int" (Tells the quotient of the division between two numbers, for instance: 4Int2=2) and the function "Rmd" (tells the reminder, for example: 9RMD2=1). To store a result in a variable, you just add an arrow and the variable after the result: 2+2->K. Now, the problems: Do this while using the least amounts of variables possible. A, B and C can't be touched. I have from D through Z to store quotients. I need those divisions to go on until a reminder hits 0. I'm puzzled as to how to do this in this basic language (my first attempt at coding something "serious", by the way). Any help would be appreciated. If you happen to need any more data, I will do my best to provide it . Cheers and thanks!!
