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

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

The answer is:

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