Properties of the Integral of Arctan

The integral of arctan has several characteristics which make it a beneficial tool in physics and calculus. Handful of these characteristics consist of:


The integral of arctan x is equivalent 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 utilizing the substitution u = 1 + x^2.


The integral of arctan x is an odd function, which means that the integral of arctan negative x is equivalent 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 handful instances of integral of arctan:


Example 1

Let us suppose we want to determine the integral of arctan x with regard to x. Applying the formula stated prior, 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 have to find the area under the curve of the arctan function between x = 0 and x = 1. Applying 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


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