## How to Solve Integrals By Trigonometric Substitution?

To solve integrals by trigonometric substitution, you have to understand first that trigonometric substitution is a complex method in integration. This substitution method of integration replaces complex integral to trigonometric function for making its calculation easy.

So following are some formulas that we replace with corresponding trigonometric functions.

$$ \text{For} \sqrt{a^2-x^2}, \;\; \text{substitue} x \;=\; a sinθ $$ $$ \text{For} \sqrt{a^2+x^2}, \;\; \text{substitue} x \;=\; a tanθ $$ $$ \text{For} \sqrt{x^2-a^2}, \;\; \text{substitue} x \;=\; a secθ $$

Solving integration by substituion using integral calculator trig sub is quite easy. But let's understand how to substitue integral by trig substituion method with an example. This will help to lear the calculation of this type of integrand.

**Example:** Calculate the following integral:

$$ \int \frac{dx}{a^2+x^2} $$

**Solution:** We may write

x = a tanθ , dx = a sec^{2}θ dθ , θ = tan^{-1}(x/a)

$$ \int \frac{dx}{a^2+x^2} \;=\; \int \frac{a sec^2θ dθ}{a^2+a^2tan^2θ} $$ $$ =\; \int \frac{a sec^2θ dθ}{a^2(1+tan^2θ)} $$ $$ =\; \int \frac{a sec^2θ dθ}{a^2 sec^2θ} $$ $$ =\; \int \frac{dθ}{a} $$ $$ =\; \frac{θ}{a} $$ $$ ⇒\; \frac{1}{a} tan^{-1}{x}{a} + C $$

So, In this way we have proved that how to substitute complex rational intergrand in terms of trigonometric substitution.
