 In this module, you will learn about symbolic techniques of integration. This module consists of four lessons.

### Other Information

 Project 2: Use trigonometric substitution to find an antiderivative of $\inline f(x)\sqrt{4-x^{2}}$ then use the anti-derivative to evaluate the definite integral $\inline \int_{-2}^{2}\sqrt{4-x^{2}}dx$. Sketch the area represented by the definite integral, give a geometric interpretation of the area, and explain how the geometric interpretation confirms the value of the definite integral.
