I just need a little help finding the antiderivative of these 2 functions:
1) f(x) = e^(u+1)
2) f(x) = sec^2(2x)
Any help is appreciated!
For the first substitute $\displaystyle v=u+1$, then $\displaystyle dv=du$ and you have $\displaystyle F(u)=\int{e}^{(u+1)}du=\int{e}^vdv=e^v+C$. Now back substitute.
