Question

y=d/dx integralcosx to 0 t/(1+t)dt

Answer 1

\[d/dx \int\limits_{0}^{cosx} \frac{ t }{ 1+t } dt\]

Answer 2

\[\frac{cosx}{1+cosx}\]

Answer 3

how did u do it?

Answer 4

@Outkast3r09 I think u made a miss take in your first step (While u made the integral)

Answer 5

the derivative of an integral is simply the integral itself with the variables in other words ... integrals and derivatives cancel eachother out

Answer 6

\[\frac{cosx}{1+cosx} \]is your answer

Answer 7

It should be\[\cos(x)-\ln(1+\cos(x))\]
