12-78.
1. Examine the integrals below. Consider the multiple tools available for integrating and use the best strategy. After evaluating each integral, write a short description of your method. Homework Help ✎

Let u = x + 1.
Once you rewrite the integrand, you should recognize it as a special case.

Let u = sin(x).

sin(2x) = 2sin(x)cos(x)

Let u = sin2(x) + 1.

ln(x2) = 2ln(x)
