  • fantastic and easy to understand. thanks!

  • If you could please provide a whiteboard on inverse trigonometric functions within implicit differentiation. Looked around the internet and couldn't find anything specific. Thank you.

  • Having a problem with the second and final portion of this problem:

    Find the function g(x) that is implicitly defined by the relation:

    sqrt x^2 - y^2 + Arc cos x/y = 0 , y dosen't equal 0,

    Answer: y = g(x) = x.

    Someone posted the following for the answer:

    g'(x)= 1/2 (x^2-y^2)^-1/2 ( 2x-2ydy/dx) + -1/sqrt(1-(x/y)^2) [ 1/y][ -x/y^2dy/dx]=0

    Was able to work up to and complete the first part using the chain rule. The answerer through me off with the cos inverse function with the y^2.
