$$\int\limits_{0}^{1} \sinh{\left(x \right)} \cosh{\left(x \right)}\, dx$$

Integral(cosh(x)*sinh(x), (x, 0, 1))

Detail solution

There are multiple ways to do this integral.
Method #1
1. Let $u = \cosh{\left(x \right)}$ .
  
  Then let $du = \sinh{\left(x \right)} dx$ and substitute $du$ :
  
  $\int u\, du$
  1. The integral of $u^{n}$ is $\frac{u^{n + 1}}{n + 1}$ when $n \neq -1$ :
    
    $\int u\, du = \frac{u^{2}}{2}$
  Now substitute $u$ back in:
  
  $\frac{\cosh^{2}{\left(x \right)}}{2}$
Method #2
1. Let $u = \sinh{\left(x \right)}$ .
  
  Then let $du = \cosh{\left(x \right)} dx$ and substitute $du$ :
  
  $\int u\, du$
  1. The integral of $u^{n}$ is $\frac{u^{n + 1}}{n + 1}$ when $n \neq -1$ :
    
    $\int u\, du = \frac{u^{2}}{2}$
  Now substitute $u$ back in:
  
  $\frac{\sinh^{2}{\left(x \right)}}{2}$
Add the constant of integration:

$\frac{\cosh^{2}{\left(x \right)}}{2}+ \mathrm{constant}$

The answer is:

$\frac{\cosh^{2}{\left(x \right)}}{2}+ \mathrm{constant}$
