We first recall that we can approximate the trigonometric functions for small angles measured in radians using s i n c o s t a n 𝑥 ≈ 𝑥, 𝑥 ≈ 1 − 𝑥 2, 𝑥 ≈ 𝑥. . We note that if 𝑥 is a small angle measured in radians, then 2 𝑥 is also a small angle measured in radians. Therefore, these approximations hold ...
