Integral(3/x - 2*sin(5*x) + 1, (x, 0, 1))

Detail solution

Integrate term-by-term:
1. Integrate term-by-term:
  1. The integral of a constant times a function is the constant times the integral of the function:
    
    $\int \left(- 2 \sin{\left(5 x \right)}\right)\, dx = - 2 \int \sin{\left(5 x \right)}\, dx$
    1. Let $u = 5 x$ .
      
      Then let $du = 5 dx$ and substitute $\frac{du}{5}$ :
      
      $\int \frac{\sin{\left(u \right)}}{5}\, du$
      1. The integral of a constant times a function is the constant times the integral of the function:
        
        $\int \sin{\left(u \right)}\, du = \frac{\int \sin{\left(u \right)}\, du}{5}$
        
        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: $\frac{2 \cos{\left(5 x \right)}}{5}$
  1. The integral of a constant times a function is the constant times the integral of the function:
    
    $\int \frac{3}{x}\, dx = 3 \int \frac{1}{x}\, dx$
    1. The integral of $\frac{1}{x}$ is $\log{\left(x \right)}$ .
    So, the result is: $3 \log{\left(x \right)}$
  The result is: $3 \log{\left(x \right)} + \frac{2 \cos{\left(5 x \right)}}{5}$
1. The integral of a constant is the constant times the variable of integration:
  
  $\int 1\, dx = x$
The result is: $x + 3 \log{\left(x \right)} + \frac{2 \cos{\left(5 x \right)}}{5}$
Add the constant of integration:

$x + 3 \log{\left(x \right)} + \frac{2 \cos{\left(5 x \right)}}{5}+ \mathrm{constant}$

The answer is:

$x + 3 \log{\left(x \right)} + \frac{2 \cos{\left(5 x \right)}}{5}+ \mathrm{constant}$

/

$$\int \left(\left(- 2 \sin{\left(5 x \right)} + \frac{3}{x}\right) + 1\right)\, dx = C + x + 3 \log{\left(x \right)} + \frac{2 \cos{\left(5 x \right)}}{5}$$
