# Integral of the Hyperbolic Cosecant Squared

In this tutorial we shall discuss the integration of the hyperbolic cosecant square function, and this integral is an important integral formula. This integral belongs to the hyperbolic formulae.

The integration of the hyperbolic cosecant square function is of the form

To prove this formula, consider

Using the derivative formula $\frac{d}{{dx}}\coth x = - {\operatorname{csch} ^2}x$, we have

Integrating both sides of equation (i) with respect to $x$, we have

As we know that by definition integration is the inverse process of the derivative, so the integral signs $\int {}$and $\frac{d}{{dx}}$ on the right side will cancel each other out, i.e.
