Integral(x^3/3 + sin(5*x)/5, (x, 0, 1))

Detail solution

Integrate term-by-term:
1. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int \frac{x^{3}}{3}\, dx = \frac{\int x^{3}\, dx}{3}$
  1. The integral of $x^{n}$ is $\frac{x^{n + 1}}{n + 1}$ when $n \neq -1$ :
    
    $\int x^{3}\, dx = \frac{x^{4}}{4}$
  So, the result is: $\frac{x^{4}}{12}$
1. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int \frac{\sin{\left(5 x \right)}}{5}\, dx = \frac{\int \sin{\left(5 x \right)}\, dx}{5}$
  1. Let $u = 5 x$ .
    
    Then let $du = 5 dx$ and substitute $\frac{du}{5}$ :
    
    $\int \frac{\sin{\left(u \right)}}{25}\, du$
    1. The integral of a constant times a function is the constant times the integral of the function:
      
      $\int \frac{\sin{\left(u \right)}}{5}\, du = \frac{\int \sin{\left(u \right)}\, du}{5}$
      1. The integral of sine is negative cosine:
        
        $\int \sin{\left(u \right)}\, du = - \cos{\left(u \right)}$
      So, the result is: $- \frac{\cos{\left(u \right)}}{5}$
    Now substitute $u$ back in:
    
    $- \frac{\cos{\left(5 x \right)}}{5}$
  So, the result is: $- \frac{\cos{\left(5 x \right)}}{25}$
The result is: $\frac{x^{4}}{12} - \frac{\cos{\left(5 x \right)}}{25}$
Add the constant of integration:

$\frac{x^{4}}{12} - \frac{\cos{\left(5 x \right)}}{25}+ \mathrm{constant}$

The answer is:

$\frac{x^{4}}{12} - \frac{\cos{\left(5 x \right)}}{25}+ \mathrm{constant}$
