Example 1
Let's say we want to determine the integral of arctan x with regard to x. Utilizing the formula mentioned above, we get:
∫ 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 between x = 0 and x = 1. Utilizing the integral of arctan, we get:
∫ 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|)
