Can someone please help me out with this problem? It is the last one I have for my calculus assignment due tomorrow! We haven't done anything like this in class, so I have NO idea what to do.
Here is a link to a picture of the problem because I couldn't type it on here.

we should do differentiation or integration??
if its deferenciation then
use the product principle rule
e^3tanx+1 * d/dx sec^2x + sec^2x * d/dx e^3tanx+1
= e^3tanx+1 * 2secx(secxtanx) + sec^2x * e^3tanx+1(3sec^2x)
then simplyfy it and substitute x as 0 and x as 45 and then add the values and divide them by 2,
you will get the answer
