Step-by-step Solution

Problem to solve:

$\int\frac{1}{\sqrt{x^2-36}}dx$

Specify the solving method

1

We can solve the integral $\int\frac{1}{\sqrt{x^2-36}}dx$ by applying integration method of trigonometric substitution using the substitution

$x=6\sec\left(\theta \right)$
2

Now, in order to rewrite $d\theta$ in terms of $dx$, we need to find the derivative of $x$. We need to calculate $dx$, we can do that by deriving the equation above

$dx=6\sec\left(\theta \right)\tan\left(\theta \right)d\theta$
