SEAMIC_Integrals: Trigonometric Integrals

In this video a trigonometric integral is solved using a specific type of substitution. This substitution involves changing variables to convert the trigonometric function into a rational one. The process requires knowledge of integration and derivatives, as well as simplifying mathematical expressions. The example shown involves a product of two trigonometric functions, sine cubed and cosine, which can be simplified by recognizing that the function is all in sine. This recognition is related to the parity of the exponent. By applying the substitution, the integral becomes more manageable, and the solution is obtained through simplification and application of mathematical properties. The video demonstrates how this change of variables can be useful in solving trigonometric integrals.
