## Frequently Asked Questions

### What is trigonometric substitution in calculus?

In calculus, the trigonometric substitution is a method of substitution in the integrals to solve them. This substitution method involves the substitution of trigonometric functions in the original function.

This technique helps to solve complex integrals. You can also use integral trigonometric substitution calculator to get desired results online.

### Why do we use trigonometric substitution?

The trigonometric substitution is used when you don’t have a perfect square root of the function. When the function becomes unable to integrate, the substitution method helps to solve it by the substitution of trigonometric functions. Use trig substitution integral calculator to get instant results with plot and graph.

## How do you integrate using trigonometric substitution?

Suppose an integral of the form ∫dx / √(a^2 - x^2 ) , we can use trigonometric substitution method to solve it.

We may substitute,

$ x\;=\;a\;sinθ \;\;,\;\;dx\;=\;a\;cosθ dθ\;\;,\;\;θ\;=\;sin^{-1}\frac{x}{a} {2}{2}lt;/p>

Then

$∫\frac{dx}{\sqrt{a^2\;-\;x^2}}\;=\;∫\;\frac{a\;cosθ\;dθ}{\sqrt{a^2\;-\;a^2 sinθ^2}}$ $∫\frac{dx}{\sqrt{a^2\;-\;x^2}}\;=\;∫\;\frac{a\;cosθ\;dθ}{\sqrt{a^2(1\;-\;sin^2\;θ)}}$ $∫\frac{dx}{\sqrt{a^2\;-\;x^2}}\;=\;∫\;\frac{a\;cosθ\;dθ}{\sqrt{a^2(cos^2\;θ)}}$ $∫\frac{dx}{\sqrt{a^2\;-\;x^2}}\;=\;∫\;\frac{a\;cosθ\;dθ}{a\;cosθ}\;=\;∫\;1d\;θ{2}{2}lt;/p>

So,

$∫\frac{dx}{\sqrt{a^2\;-\;x^2}}\;=\;θ\;+\;C{2}{2}lt;/p>

Now substituting the value of θ

$∫\frac{dx}{\sqrt{a^2\;-\;x^2}}\;=\;sin^{-1}\;\frac{x}{a}\;+\;C{2}{2}lt;/p>

### Are trig functions polynomials?

No, the trigonometric functions are not polynomials. Even if these function involves variables, there can’t be known as polynomials. Polynomial functions also doesn’t involve trigonometric functions. You can use integration of trigonometric functions calculator if you want to solve them online.

### Are trig functions differentiable?

Yes, you can differentiate trig functions by using the definition of derivatives. There are also many theorems based on the differentiation of trig function for example, the function sin x is differentiable everywhere. With trig integral calculator, you can calculate trig functions free online.

### What trig functions are undefined?

The trig functions can be undefined on different case of angle values. For example if x=0 for sin x, the function becomes zero. Or if we take x=0 for cosecx, which is the reciprocal of sin x. gives the undefined value as the denominator is zero.
