Integral of inverse cosecant it is an important integral function, but it has no direct method to find we shall find the integration of cosecant inverse by using integration by parts method.
The integral of cosecant inverse is of the form
To solve this integration, it must have at least two functions, it in this function it has only one function that is , now consider second function as . Now the integration becomes
Take first function is and second function will be
Using formula for integration by parts, we have
Equation (i) becomes using above formula, we have
It can be written in the form, we get
Now further we can use this integration of cosecant inverse as a formula.
