Powers of the Trig Functions:
1) Integrals of the form: (sin" x cos" x dx m or n odd
Strategy: If m is odd, save a sine factor and convert to cosine
If n is odd, save a cosine factor and convert to sine
2) Integrals of the form: [sin">
Strategy: use angle identities:
1+ cos(2x)
2
2
cos² x =
[sin" x cos" x dx m and n even and non-negative
2
-; sin′x=
1-cos(2x)

3) Integrals of the form: [sec" x tan" x dx ; if m is even
Strategy: Save a sec² x and convert to tangent
4) Integrals of the form: [sec" x tan" x dx; if n is odd
Strategy: Save a secx tanx and convert to secant
5) Stan" x dx n any positive integer
Strategy: convert a tan² x to sec²x-1 and distribute; repeat if necessary
6) [sec" x dx ; mis odd
Strategy: Integrate by parts
*** If all else fails convert everything to sines and cosines
