    (solved for now!) I'm having some issues getting to where my mathbook wants me

    with a few problems from my suggested assignments.

    I'm taking a calculus class, which at this point is looking like a mistake, as my algebra skills are shaky at best.



    is the first problem I'm having issues with.

    I believe I'm correct up to where I've gotten but can't be sure. This is what I have towards the answer so far:

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

    That is what I have come to by using the product rule.

    Any help would be greatly appreciated!

    What you have for dy/dx so far is fine. Now convert back to radicals.

    Incredible. That was all I needed to get me to where the book wanted me. Thanks a bunch.
    I'm going to mark it as solved, and maybe open it up again later if I need to.

    Thanks again, I'm super happy it only took advice in words, not numbers to get me through it!
