## Properties of the Integral of Arctan

The integral of arctan has many characteristics that make it a useful tool in physics and calculus. Handful of these properties include:

The integral of arctan x is equal to x times the arctan of x minus the natural logarithm of the absolute value of the square root of one plus x squared, plus a constant of integration.

The integral of arctan x can be shown as the terms of the natural logarithm function using the substitution u = 1 + x^2.

The integral of arctan x is an odd function, this implies that the integral of arctan negative x is equal to the negative of the integral of arctan x.

The integral of arctan x is a continuous function which is defined for all real values of x.

## Examples of the Integral of Arctan

Here are few examples of integral of arctan:

Example 1

Let’s assume we want to find the integral of arctan x with concern to x. Utilizing the formula mentioned earlier, we get:

∫ arctan x dx = x * arctan x - ln |√(1 + x^2)| + C

where C is the constant of integration.

Example 2

Let's assume we want to figure out the area under the curve of the arctan function between x = 0 and x = 1. Utilizing the integral of arctan, we achieve:

∫ from 0 to 1 arctan x dx = [x * arctan x - ln |√(1 + x^2)|] from 0 to 1

= (1 * arctan 1 - ln |√(2)|) - (0 * arctan 0 - ln |1|)

= π/4 - ln √2

As a result, the area under the curve of the arctan function between x = 0 and x = 1 is equivalent to π/4 - ln √2.
