Hey geek... completely normal and stylish people, please help me with math.

With wich "x"  values binomial "3x-1" acquires positive values?

 

 

heres some hd patatoes :

 

[Sauron]

3x -1 > 0

3x > 1

x > 1/3

 

 

-edit-

 

if you think that's hard...

 

try calculating the volume of the rotatory solid of y=√log(x+1) for x part of [0,e-1]

[xnoobftw]

You can probably do some mental calculations... If not expand everything out.

I dont think you can apply binomial to just 3x-1

It has been 84 years since i did highschool math

[PhilBoisvert]

uhhh x > 1/3...

 

You are gonna have a haaaard time if you struggle with that. How old are you?

@Sauron

 

Yup basic equation.

 

 

How old are you OP?

I missed a lot of classes in one grade(or i just dont remember shit.)..wich was very important. Well atleast i have this forum <3

your age is more then 84?

@Laurysss

Stop harrasing the elderly here in LTT

 

Just kidding , i make retarded jokes. Sorry :"

[PhilBoisvert]

This is the shit I have to deal with! Finished thi course at 95% best note of the class. I love math soo much. Futur civil engeneer here. If you have any more question just ask.

 

[Laurysss]

@Sauron dont laugh.

 

For example 1:3 your answer was 1/3 but when you calculate it normally it is 0.3. Should i do the same for 5:3?

@PhilBoisvert

 

I haven't done calc 1 in college.

I just would like to suck on your brain until i get more then 6 from maths..

@Laurysss

 

1:3 = 1/3. It's the same thing by definition. The division results in 0.333333... etc (recursive 3s), which can be rounded up (but is not equal) to 0.3. I write it in fraction form so I don't give an inaccurate answer by rounding up.

 

5:3 = 5/3.

I live in quebec so our class are not named calculus. I did the equivalent (and a lot more in dept in the differetial equation) of calculus 1 and 2 at same time, I finished 1 at 95% and 2 (the  one with differential equation) at 91%. It suck because I would like to learn more but thos were the only math course I ad to do. Now I am in the advanced physics stuff like fluid dynamics,  concrete and steel resistence to design structure.

Ooooh I remember doing that last semester. I'm taking aerospace engineering. Where do you go to?

[Laurysss]

@Sauron @PhilBoisvert i missed all the fraction shit so here i am...

1:1/9

 

is it 9?

[PhilBoisvert]

@Laurysss

 

1:3 = 1/3. It's the same thing by definition. The division results in 0.333333... etc (recursive 3s), which can be rounded up (but is not equal) to 0.3. I write it in fraction form so I don't give an inaccurate answer by rounding up.

 

5:3 = 5/3.

There is a point where is just way more convenient to express everthing in fraction. Way more accurate for long problem. I usually just round the final answer. Save them in my calculator. TI Nspire is life

ÉTS (École de technologie supérieur) in Montréal. Great school. My roomate is doing aerospace to, Seems fun.

@PhilBoisvert I don't get to use graphical calculators in university ^^ used to in high school though

 

@Laurysss yes, y/(y/x) = x

as well as

a/b * c/d = ac/bd

a/b / c/d = ad/bc

a/b + c/b = (a+c)/b

Yes learned everything by hand first. The main difference is where you will have one long hard integral to do, I will have 3-4. It is a choice of my school to use these calculator.

i am actually not that dumb.. wow.

OH. MY. GOD.

Was hoping I didn't have to see triple integrals anymore....what have you done!?

Finding the limits of integration is a pain in the ass with multi-variables.

In other note, find the Magnetic Field by using Maxwell's Equations + Curl-Curl + partial derivatives... X.x

That actually looks like a potato.
