Trig Sub: Integration with Trigonometric Substitution 1, Single Variable Calculus

(Part 1 of 2) We discuss how to use trig sub to evaluate integrals that contain expressions like x^2 + a^2, x^2 - a^2, and a^2 - x^2. Our focus is on understanding the geometry of the problem. There are four examples in this part.
