Question:

Use the substitution {eq}x = \frac{6}{5} \tan t {/eq} to transform the integral {eq}I = \int \frac{dx}{\sqrt {25x^2 + 36}} {/eq} into a trigonometric integral.

{eq}I = \int {/eq} _____ dt

Evaluation of Integral:

Integration is reverse of differentiation.It is also called anti derivative.

Here, we are going to use substitution method to evaluate the integral.

Add constant c at the end of evaluation.
