I am having trouble taking the derivative of the following:
t(4-t^2)^(1/2)
I can't decide if you need to use the product rule or not.
What I did is used the PR to get
(4-t)^1/2)*1t^2*(4t-1)^(-1/2)
Is this correct?
you do.
f= t(4-t^2)^.5
f'= (4-t^2)*.5 + .5t/(4-t^2)^.5 * 2t/1
I can't reconcile yours with mine
if g=uv
g'= u'*v+ v'*u
