## Properties of the Integral of Arctan

The integral of arctan has several characteristics which make it a useful tool in calculus and physics. 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 applying the substitution u = 1 + x^2.

The integral of arctan x is an odd function, which 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 that is defined for all real values of x.

## Examples of the Integral of Arctan

Here are some instances of integral of arctan:

Example 1

Let’s assume we have to determine the integral of arctan x with regard to x. Applying the formula stated above, we achieve:

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

where C is the constant of integration.

Example 2

Let's say we want to find the area under the curve of the arctan function within x = 0 and x = 1. Applying the integral of arctan, we obtain:

∫ 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

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