Homework Statement
Let f(x) = sqrt(4-x2) + 2cos-1(x/2)
Then f '(x) can be written in simplified form -[(x+c)/(mx+n)]p
NOTE: I'm not sure if that negative is supposed to be there since my book is smudged.
What are the values of c, m, n, and p?
Homework Equations
Derivative of cos-1(x) is -1/(sqrt(1-x2)
The Attempt at a Solution
I found the derivative to be -x/sqrt(4-x2) - 1/sqrt(1-(x/2)2)
My problem is that I have no idea how to simplify it into that form. Can anyone offer me some assistance on this question?
Thanks in advance!
