The 6 basic hyperbolic functions are defined by:

Example 1: Evaluate the integral ∫sech2(x)dx

Solution:

We know that the derivative of tanh(x) is sech2(x), so the integral of sech2(x) is just:

tanh(x)+c.

Example 2: Calculate the integral .

Solution :We make the substitution: u = 2 + 3sinh x, du = 3cosh x dx. Then cosh x dx = du/3.

Hence, the integral is

Example 3: Calculate the integral ∫sinh2x cosh3x dx

Solution: Applying the formulas and , we get:

Example 4: Evaluate ∫ x sech2 x dx.

Solution:
