Homework Statement e^y = x(y-1) answer must be in implicit form Homework Equations The Attempt at a Solution I literally have no idea how to do this problem. I have the answer, but that's it. The answer is dy/dx(e^y) = x(dy/dx) + y - 1

yep its y'= 3x-10 / root(x^2-5)^3. Thanks you soooo much.

jesussss... I'm just being so dumb leme do this problem fifteen times before I write anything else so I can cease to waste your time.

jesus christ I am sorry

oh alright, 3x-10/ x^2-5 I was just made a whole bunch of little errors. thanks. Yeah I was writing it out but I guess I am just a little tired.

It's

I multiplied both the numerator and the denominator by the square root of x squared minus 5. I have to get use to this equation writing thing. It's quite hard otherwise.

(2x^2 -10) -2x^2 +3/2 ---------------------------------- x^2 -5*squareroot(x^2 -5)

using the chain rule shouldn't you have (1/2)(2x-3)(x^2-5)^-1/2 *2x?

cool, thanks for the tip, would my answer happen to be correct?

new answer -23/2 /(x^2-5)

f'(x)=2 g'(x)=1/2(x^2-5)^-1/2 *2x

(x^2-5)^(1/2) *2 - 1/2(x^2-5)^(-1/2) *2x ------------------------------------------------- x^2-5

(x^2-5)^1/2=g(x); f(x)=2x-3 I understand how to plug everything in I just am having problems with simplifying I suppose.

Mod note: To reduce confusion, I fixed the erroneous correction.[/color] my fault yes I accidentally wrote the nine.
