WebIn equation cosxsinx=sinx 2cosx we shouldn’t divide by cosx because we might lose solutions( cosx=0) . Correct. if we do we are essentially dividing by zero, how is this possible? How is what possible? You said it yourself: by dividing by cos(x), you are assuming cos(x) to be non-zero, and therefore ignoring the solution cos(x)=0.
