Based on your comment to another answer, you want to show that $\displaystyle \int \mathrm{sech}^2 x dx = \tanh x + c$.. I find the easiest way is to use complex numbers. Start with the circular trigonometric version $\displaystyle \int \sec^2 x dx = \tan x + c$, which I assume you can assume or you know how to prov

Mathematically, we can write the formula for the derivative of root x as d (√x)/dx = (1/2) x -1/2 or 1 (/2√x). The formula for the power rule of derivatives is d (x n )/dx = n x n-1, where n ≠ -1. Using this formula and substituting n = 1/2, we can get the derivative of root x. Further, in this article, we will explore the derivative ofKalkulus.

Answers to the question of the integral of 1 x 1 x are all based on an implicit assumption that the upper and lower limits of the integral are both positive real numbers. If we allow more generality, we find an interesting paradox. For instance, suppose the limits on the integral are from −A − A to +A + A where A A is a real, positive number.
