Evaluate the integrals in Exercises 1–14.
∫ (2 dx) / √(1 - 4x²) from 0 to 1/(2√2)

Use any method to evaluate the integrals in Exercises 15–38. Most will require trigonometric substitutions, but some can be evaluated by other methods.

∫ (x² dx) / (4 + x²)

The integrals in Exercises 1–44 are in no particular order. Evaluate each integral using any algebraic method, trigonometric identity, or substitution you think is appropriate.

∫ (dx / ((2x + 1)√(4x + 4x²)))

In Exercises 39–48, use an appropriate substitution and then a trigonometric substitution to evaluate the integrals.
