Hi, it has been a while since I done some differentiation and a little
help would be appreciated.
The function is f(x) = k /((1+x/12)^n)
Where k is a constant value and n = 0 -> infinity
What is the derived function for f(x):
f'(x) = -n*k*(1+x/12)^(-n-1)
The chain rule requires that you multiply by the derivative of 1 + x/12.
f'(x) = -n*k*(1+x/12)^(-n-1)*(1/12)
= -n*k/(12*(1+x/12)^(n+1))
.
