Can someone please give me the full detailed solutions for both problems? The questions are to find the derivative functions of these functions (using the quotient rule).
y = (r^2)/(1 + sqrt(r))
f(x) = x/(c + c/x)
Answer (1): y' = r(4 + 3sqrt(r))/2(1 + sqrt(r))^2
Answer (2): y' = 2cx/(x^2 + c)^2
Any help would be greatly appreciated!
Thanks in advance!
