WebApr 18, 2014 · $\begingroup$ Warning: Squaring equations introduces spurious solutions; all solutions must be checked in the equations before one is done. In this particular case, the "other" square root gives $\sin \theta = - \frac{4}{5}$, which is not mentioned, which (unsurprisingly) when checked is not a solution of the equation. 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 ... boise id to tacoma wa
