Often, if the argument is simple enough, the function value will be written without parentheses, as sin θ rather than as sin(θ).. Each of sine and cosine is a function of an angle, which is usually expressed in terms of radians or degrees.Except where explicitly …

WebJan 1, 2024 · Which is a very good approximation in most circumstances. Convert 1 ° into radians, giving θ ≈ 0.01745 rad. sin ( θ) is also approximately this value so the small angle approximation holds. This formula only works for angles measured in radians because the Taylor series is different if it is measured in degrees.
