Why? • Allows you to evaluate integrals involving • Oh you meant why am I making you do this? It is part of the curriculum for all Calc II classes in college…
How? • Using right triangles…
How? • Using right triangles…
How? • Using right triangles…
Procedure • Write down the substitution for x, calculate dx, and specify the selected values of for the substitution. • Make the substitution into the integrand and simplify algebraically. • Integrate the trig integral keeping in mind the restrictions on the angle . • Draw an appropriate reference triangle to reverse the substitution in the integration result and convert back to the original variable x.
