# Evaluate the integral \int \frac{x}{\sqrt{9-4x^2}} \,dx

## Question:

Evaluate the integral {eq}\int \frac{x}{\sqrt{9-4x^2}} \,dx {/eq}

## Integral:

The problem can be solved by using the substitution where we will put {eq}9-4x^{2}=t {/eq} and then differentiate it to get the value of dx and then put it in the integral and then integrate using the exponential rule.
