Integral(2*sin(5*x) + (3*cos(x))/2, (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:
  
  $\int 2 \sin{\left(5 x \right)}\, dx = 2 \int \sin{\left(5 x \right)}\, dx$
  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:
      
      $\int \sin{\left(u \right)}\, du = \frac{\int \sin{\left(u \right)}\, du}{5}$
      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: $- \frac{2 \cos{\left(5 x \right)}}{5}$
1. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int \frac{3 \cos{\left(x \right)}}{2}\, dx = \frac{\int 3 \cos{\left(x \right)}\, dx}{2}$
  1. The integral of a constant times a function is the constant times the integral of the function:
    
    $\int 3 \cos{\left(x \right)}\, dx = 3 \int \cos{\left(x \right)}\, dx$
    1. The integral of cosine is sine:
      
      $\int \cos{\left(x \right)}\, dx = \sin{\left(x \right)}$
    So, the result is: $3 \sin{\left(x \right)}$
  So, the result is: $\frac{3 \sin{\left(x \right)}}{2}$
The result is: $\frac{3 \sin{\left(x \right)}}{2} - \frac{2 \cos{\left(5 x \right)}}{5}$
Add the constant of integration:

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

The answer is:

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

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