The small angle approximation has to be worked out in radians. The three formulas for small angle approximation are: sin θ ≈ θ tan θ ≈ θ cos θ ≈ 1 - θ 2 2. st andrews peregian feesWebbthe previous approximations developed by Aki and Richards (1980). They are developed by expanding the Aki-Richards approximation in a power series of the sine of incidence angle. Thus, these formulae are limited from the very beginning to small changes in medium parameters. Wang (1999), on the other hand, starts the whole approach with the exact st andrews peregianWebbFor a small angle 𝑥 measured in radians, we can approximate the outputs of the trigonometric function as follows: s i n 𝑥 ≈ 𝑥, c o s 𝑥 ≈ 1 − 𝑥 2 , t a n 𝑥 ≈ 𝑥.
