Solve Trigonometric Equation Double Angle Formula
In this video I will show you how to solve a trigonometric equation using the double angle for cosine. When applying the double angle of cosine we are given a quadratic equation where we will now need to factor and solve using the zero product property. We will then determine the solutions on the interval [0,2pi) and all solutions. I make short ...
