  1. Lecture 12 – Trig Integrals Use u-sub, trig identities, and/or by parts.

  2. Trig identities:

  3. Example 1

  4. Example 2

  5. With dealing with sine or cosine functions, you are looking for (cos x dx) or (sin x dx), respectively. Example 3

  6. Example 4

  7. Lecture 13 – More Trig Integration With dealing with tangent or secant, you are looking for (sec2 x dx) or (sec x tan x dx), respectively. Example 5

  8. Example 6

  9. Example 7

  10. When faced with one of the above in an integral , create a • right triangle and substitute trig expressions in  for algebraic • expressions of x. (unless a simple u-substitution is available) Trig Substitution
