WebApr 27, 2016 · 7,583 2 19 38. Add a comment. 1. Intuitively cos ( − θ) measures the x -coordinate of a vector that measures θ degrees below the positive x -axis, so this is why we have cos ( − θ) = cos θ. Another way of seeing this is through the series representation of cos x given by. cos ( − x) = 1 − ( − x) 2 2! + ( − x) 4 4! − ( − x) 6 ... WebAnswer (1 of 10): The 1 − cos function was historically a very practical function, so much so that it was given its own name, the versed sine, with symbol versin. Therefore versin θ = …
