$$\int\limits_{0}^{1} \left(- \sin{\left(10 x \right)} + \cos{\left(19 x - 2 \right)}\right)\, dx$$

Integral(cos(19*x - 2) - sin(10*x), (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:
  
  $\int \left(- \sin{\left(10 x \right)}\right)\, dx = - \int \sin{\left(10 x \right)}\, dx$
  1. Let $u = 10 x$ .
    
    Then let $du = 10 dx$ and substitute $\frac{du}{10}$ :
    
    $\int \frac{\sin{\left(u \right)}}{10}\, du$
    1. The integral of a constant times a function is the constant times the integral of the function:
      
      $\int \sin{\left(u \right)}\, du = \frac{\int \sin{\left(u \right)}\, du}{10}$
      1. The integral of sine is negative cosine:
        
        $\int \sin{\left(u \right)}\, du = - \cos{\left(u \right)}$
      So, the result is: $- \frac{\cos{\left(u \right)}}{10}$
    Now substitute $u$ back in:
    
    $- \frac{\cos{\left(10 x \right)}}{10}$
  So, the result is: $\frac{\cos{\left(10 x \right)}}{10}$
1. Let $u = 19 x - 2$ .
  
  Then let $du = 19 dx$ and substitute $\frac{du}{19}$ :
  
  $\int \frac{\cos{\left(u \right)}}{19}\, du$
  1. The integral of a constant times a function is the constant times the integral of the function:
    
    $\int \cos{\left(u \right)}\, du = \frac{\int \cos{\left(u \right)}\, du}{19}$
    1. The integral of cosine is sine:
      
      $\int \cos{\left(u \right)}\, du = \sin{\left(u \right)}$
    So, the result is: $\frac{\sin{\left(u \right)}}{19}$
  Now substitute $u$ back in:
  
  $\frac{\sin{\left(19 x - 2 \right)}}{19}$
The result is: $\frac{\sin{\left(19 x - 2 \right)}}{19} + \frac{\cos{\left(10 x \right)}}{10}$
Now simplify:

$\frac{\sin{\left(19 x - 2 \right)}}{19} + \frac{\cos{\left(10 x \right)}}{10}$
Add the constant of integration:

$\frac{\sin{\left(19 x - 2 \right)}}{19} + \frac{\cos{\left(10 x \right)}}{10}+ \mathrm{constant}$

The answer is:

$\frac{\sin{\left(19 x - 2 \right)}}{19} + \frac{\cos{\left(10 x \right)}}{10}+ \mathrm{constant}$

$$\int \left(- \sin{\left(10 x \right)} + \cos{\left(19 x - 2 \right)}\right)\, dx = C + \frac{\sin{\left(19 x - 2 \right)}}{19} + \frac{\cos{\left(10 x \right)}}{10}$$
