How can you do the integration of sin x?
Yes, please do.
Alright. Let u = cos x, then du/dx = -sin x dx. We can rewrite the integral as ∫-sin(x) * sin(x)dx/u and then substitute u into it. This gives us -∫du/u = -ln|u| + C = -ln|cos(x)| + C, where C is the constant of integration. Therefore, the final answer would be -ln|cos(x)| + C.
