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

The integration of 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 further we can solve this result as follows,

So in conclusion we can write this formula as
