$\int - cos e c^{2} x d x = cot x + C$ $int-cosec^2xdx=cotx+C$

This is a standard form of one of the trigonometric integrals and can be written directly as

$\int - cos e c^{2} x d x = - \int cos e c^{x} d x = cot x + C$ $int-cosec^2xdx=-intcosec^xdx=cotx+C$

This is true since $\frac{d}{d x} cot x = - cos e c^{2} x$ $d/dxcotx=-cosec^2x$
