Can someone do this for me? (Maths)

[Nineshadow]

I know this : x =   , where i , n and AB are variables.

 

I need to calculate n.

 

It's 12 AM and I'm really tired. Tomorrow I'll have to spend 11 hours at school (from 9AM to 8PM) and I need to finish two projects at literature(finished) and physics(almost finished). As you can imagine, this is related to the physics one.

(calculating the index of refraction of glass from the deviation suffered by the light when it passes through a parallel glass plane)

 

It's just lots of algebra and I'm really sleepy... I know how to do it but it's too much right now.I got to :

n = sqrt(sin^2(i) * ( d^2 - (dsin(i))^2 - ( dsin(i) - Δ)^2) / ( dsin(i) - Δ)

Δ = x

AB = d

For future reference this is a good app and does work. https://photomath.net/

there is no calculus in this, just algebra. and it is rather simple too.

No photomath can not solve this, it is not a numerical problem.

Do your own homework! (the answer is 7)

 

EDIT:fixed my homophones

Doesn't solve stuff like this.

Whatever.I've been awake since 7 AM , after 7 hours of school and it's 12 AM.Sleeping is all I want right now.

i did a thing

 

pic coming in a min

 

btw, it may be 100% wrong b/c i have also been awake since 7am and have also had school today (Double Physics and Double Chemistry and one History) so yeah...

 

 

 

EDIT: Yep, did the sin^-2 bit wrong i think and shit, I list a square root in a transcription error (bottom of fraction)

do you're own homework! (the answer is 7)

You're the one who should be doing their homework lad, can't even get homophones right

[Sauron]

n = (sin(i)cos(i))/(sin(i) - x/AB)) + sin(i)

 

or

 

n = - ((sin(i)cos(i))/(sin(i) - x/AB)) + sin(i))                          

 

(if it's physics usually the negative result gets discarded, but I put it in regardless for the sake of math ^^)

 

hopefully I ddn't mess it up, my pen died and I had to do it in my mind -.- @Nineshadow (make sure you do all your hw yourself next time though )

[LancerBG]

math with letters and weird squiggly things, fuck that! I'll stick to gambling. Kudos for you smart fucks.

fixed lol  clearly I wasn't paying attention. Also this keyboard sucks balls.

Try with this : 

I accidentally uploaded another picture the first time.I've edited my post in the meanwhile.

 

It's the same thing though.

 

Thanks anyway.

Bearing in mind this is without any cancellation effort, I got this:

 

 

It is of course mentioning at this time that I am useless at this

I dunno if you're still working on this, but the x/AB shouldn't be inside the arcsine. It's just being multiplied.

As far as I can tell, it should be:
