# Cosecant Integral Formula

In this tutorial we will prove the formula of cosecant integral which is another important formula in integral calculus. This integral belongs to the category of trigonometric integral formulae.

The integration of the cosecant function is of the form

To prove this formula, consider

By multiplying and dividing the relation

Here , then

Now using the formula of integration , we have

Now we can further solve this result as follows:

In conclusion, we can write this formula as
