Question 1

What do we do with trigonometric integrals when at least one power is odd

Answer 1

We substitute u = the other trig function (either with an even power or completely absent from the expression)

Question 2

What do we do with trigonometric integrals when neither power is odd

Answer 2

Use a half angle trig identity

Question 3

What do we do with trigonometric integrals when the power of tangent is odd

Answer 3

We use u = sec(x), du = sec(x)tan(x)

Question 4

What do we do with trigonometric integrals when tangent and secant have even exponents

Answer 4

Set u = tan(x)
