Advanced Mathematics - Antiderivative types - odd and even powers

Antiderivative types - odd and even powers

We can use the double angle formulae, [1] to convert these functions to a
form that is easy to anti differentiate.

cos 2ax = cos2 ax - sin2 ax = 2cos2 ax - 1 = 1 - 2sin2 ax

sin_ ax_ = 1/2 (1 - cos2_ ax_)

cos_ ax_ = 1/2 (1 + cos2_ ax_)
