Combining all parts of the integral, we get

Quite a problem. It certainly is much nicer if the sin or cos has an odd exponent.

We now examine the integrals involving tan x sec x. Before we start, we will make two notes: (1) whatever
n
we say for tan-sec goes for cot-csc, and (2) tan-sec and cot-csc are grouped together whether for trig identities
or trig integrals.
