Using Small Angle Approximations

This video discusses how to simplify complicated formulas by using small angle approximations for trigonometric functions. The trick is to look for clues in the question indicating when theta is small. The speaker walks through an example problem, demonstrating how to substitute the small angle formulas for the trig functions and simplify the equation. At the end, the equation is rearranged to match the desired form. The video ends with a call to practice and work on MCQs.
