Solve each of the integrals in Exercises 39鈥74. Some integrals require trigonometric substitution, and some do not. Write your answers as algebraic functions whenever possible.
Why is it okay to use a triangle without thinking about the unit circle when simplifying expressions that result from a trigonometric substitution withor ? Why do we need to think about the unit circle after trigonometric substitution with ?
Consider the integral .
(a) Solve this integral by using u-substitution.
(b) Solve the integral another way, using algebra to multiply out the integrand first.
(c) How must your two answers be related? Use algebra to prove this relationship.
Complete the square for each quadratic in Exercises 28鈥33. Then describe the trigonometric substitution that would be appropriate if you were solving an integral that involved that quadratic.
Examples: Construct examples of the thing(s) described in the following. Try to find examples that are different than any in the reading.
(a) An integral with which we could reasonably apply trigonometric substitution with .
(b) An integral with which we could reasonably apply trigonometric substitution with .
(c) An integral with which we could reasonably apply trigonometric substitution with .
