$$\int\limits_{0}^{0} \left(- \frac{1 \cdot 5 \sin{\left(x \right)}}{\cos^{2}{\left(x \right)}} + 4\right)\, dx$$

Integral(4 - 5*sin(x)/(cos(x)^2), (x, 0, 0))

Detail solution

Integrate term-by-term:
1. The integral of a constant is the constant times the variable of integration:
  
  $\int 4\, dx = 4 x$
1. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int \left(- \frac{1 \cdot 5 \sin{\left(x \right)}}{\cos^{2}{\left(x \right)}}\right)\, dx = - \int \frac{5 \sin{\left(x \right)}}{\cos^{2}{\left(x \right)}}\, dx$
  1. The integral of a constant times a function is the constant times the integral of the function:
    
    $\int \frac{5 \sin{\left(x \right)}}{\cos^{2}{\left(x \right)}}\, dx = 5 \int \frac{\sin{\left(x \right)}}{\cos^{2}{\left(x \right)}}\, dx$
    1. Don't know the steps in finding this integral.
      
      But the integral is
      
      $\frac{1}{\cos{\left(x \right)}}$
    So, the result is: $\frac{5}{\cos{\left(x \right)}}$
  So, the result is: $- \frac{5}{\cos{\left(x \right)}}$
The result is: $4 x - \frac{5}{\cos{\left(x \right)}}$
Add the constant of integration:

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

The answer is:

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