+ # Trigonometric Equations Pathway

Have you ever wondered why a ladder placed against a wall might sometimes slide and at other times stay still? Although this is a physics problem, physicists need to understand the mathematics behind the equations in order to solve it. In the Trigonometric Equations pathway you will learn how to do just that by gaining an understanding of concepts such as Inverse Sine.
