∫ 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 figure out the area under the curve of the arctan function within 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

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