7. Antiderivatives & Indefinite Integrals

Evaluate the integrals in Exercises 69–134. The integrals are listed in random order so you need to decide which integration technique to use.

∫ (sin5t) dt / [1 + (cos5t)²]

Evaluate the integrals in Exercises 69–134. The integrals are listed in random order so you need to decide which integration technique to use.

133. ∫ (sin²x) / (1 + sin²x) dx

Evaluate the integrals in Exercises 33–54.

∫₀^(π/4) (1 + e^(tan θ)) sec²θ dθ

7. What integrals lead to logarithms? Give examples. What are the integrals of tan x, cot x, sec x, and csc x?

Use reduction formulas to evaluate the integrals in Exercises 41–50.
