A couple of remarks about notation. One should write $\sin x$ (with a space) or $\sin(x)$, not sinx. If the argument is followed by another factor, then the argument should be wrapped in parentheses. For example, $\sin x\cos x$ can theoretically be parse either as $\sin(x)\cos(x)$ or as $\sin(x\cos(x))$, but $\sin(x)\cos(x)$ clearly shows that the argument of sine is just $x$.
