Properties of the Integral of Arctan
The integral of arctan has multiple characteristics which make it a beneficial tool in physics and calculus. Some 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 expressed in terms of the natural logarithm function applying the substitution u = 1 + x^2.
The integral of arctan x is an odd function, this 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 that is defined for all real values of x.
Examples of the Integral of Arctan
Here are some examples of integral of arctan:
Example 1
Let’s assume we want to find the integral of arctan x with regard to x. Using the formula mentioned 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 have to find the area under the curve of the arctan function between x = 0 and x = 1. Using 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
As a result, the area under the curve of the arctan function between x = 0 and x = 1 is equal to π/4 - ln √2.
