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.
