Trigonometry and Polynomial Practice Problem

For today’s video, I will go over a practice problem that requires your understanding of trigonometry and polynomial. Common standardized math test questions like to test your understanding of identities, whether it be a trigonometric identity or algebraic identity. A key equation that you should know is a^2+b^2 = (a+b)(a-b) You should also remember sin^2θ + cos^2θ = 1 This problem

Problem of the video: Simplify (sin^4θ-cos^4θ)/(cos^2θ-sin^2θ)
