$$\int\limits_{0}^{1} \frac{7 \sin^{3}{\left(x \right)} + 5}{\sin^{2}{\left(x \right)}}\, dx$$

Integral((7*sin(x)^3 + 5)/sin(x)^2, (x, 0, 1))

Detail solution

Rewrite the integrand:

$\frac{7 \sin^{3}{\left(x \right)} + 5}{\sin^{2}{\left(x \right)}} = \frac{7 \sin^{3}{\left(x \right)}}{\sin^{2}{\left(x \right)}} + \frac{5}{\sin^{2}{\left(x \right)}}$
Integrate term-by-term:
1. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int \frac{7 \sin^{3}{\left(x \right)}}{\sin^{2}{\left(x \right)}}\, dx = 7 \int \frac{\sin^{3}{\left(x \right)}}{\sin^{2}{\left(x \right)}}\, dx$
  1. Don't know the steps in finding this integral.
    
    But the integral is
    
    $- \cos{\left(x \right)}$
  So, the result is: $- 7 \cos{\left(x \right)}$
1. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int \frac{5}{\sin^{2}{\left(x \right)}}\, dx = 5 \int \frac{1}{\sin^{2}{\left(x \right)}}\, dx$
  1. Don't know the steps in finding this integral.
    
    But the integral is
    
    $- \frac{\cos{\left(x \right)}}{\sin{\left(x \right)}}$
  So, the result is: $- \frac{5 \cos{\left(x \right)}}{\sin{\left(x \right)}}$
The result is: $- 7 \cos{\left(x \right)} - \frac{5 \cos{\left(x \right)}}{\sin{\left(x \right)}}$
Now simplify:

$- \frac{7 \sin{\left(x \right)} + 5}{\tan{\left(x \right)}}$
Add the constant of integration:

$- \frac{7 \sin{\left(x \right)} + 5}{\tan{\left(x \right)}}+ \mathrm{constant}$

The answer is:

$- \frac{7 \sin{\left(x \right)} + 5}{\tan{\left(x \right)}}+ \mathrm{constant}$

$$\int \frac{7 \sin^{3}{\left(x \right)} + 5}{\sin^{2}{\left(x \right)}}\, dx = C - 7 \cos{\left(x \right)} - \frac{5 \cos{\left(x \right)}}{\sin{\left(x \right)}}$$
