WebIf so, then that's an extra solution on top of tanx = 2 solutions. If not, then you can safely divide by cosx and forget about x = pi/2 or -pi/2. If you want to be totally safe, do. sinx - 2cosx = 0. Now use the Rsin (x - a) method to rewrite sinx - 2cosx. The equation Rsin (x-a) = 0 is then trivial to solve. Cosx = 0 was the possible problem I ...
