Evaluate the following integrals:
Tip – If f1(x) and f2(x) are two functions, then an integral of the form can be INTEGRATED BY PARTS as
where f1(x) and f2(x) are the first and second functions respectively.
Taking f1(x) = tanx and f2(x) = e2x in the second integral and keeping the first integral intact,
, where c is the integrating constant
