Integrating Problem: Solve Questions Using Formula for \int [f(x)]^nf(x)

[ngkamsengpeter]

Please help me to solve the following questions using $$\int [f(x)]^nf(x)=\frac{[f(x)]^{n+1}}{n+1}$$
$$\int tan {2x} dx$$

What is an integration problem doing in the pre-calculus forum?

Anyway, try writing it as sin over cos, and then use a substitution.

Are you really asked to use only the power law? Well, I guess you could use Taylor Series.
