Integral(x*y*sin(2*y) + x*sin(y)^2 - 1*4, (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:
  
  $\int x y \sin{\left(2 y \right)}\, dx = y \sin{\left(2 y \right)} \int x\, dx$
  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: $\frac{x^{2} y \sin{\left(2 y \right)}}{2}$
1. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int x \sin^{2}{\left(y \right)}\, dx = \sin^{2}{\left(y \right)} \int x\, dx$
  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: $\frac{x^{2} \sin^{2}{\left(y \right)}}{2}$
1. The integral of a constant is the constant times the variable of integration:
  
  $\int \left(\left(-1\right) 4\right)\, dx = - 4 x$
The result is: $\frac{x^{2} y \sin{\left(2 y \right)}}{2} + \frac{x^{2} \sin^{2}{\left(y \right)}}{2} - 4 x$
Now simplify:

$\frac{x \left(2 x y \sin{\left(2 y \right)} - x \cos{\left(2 y \right)} + x - 16\right)}{4}$
Add the constant of integration:

$\frac{x \left(2 x y \sin{\left(2 y \right)} - x \cos{\left(2 y \right)} + x - 16\right)}{4}+ \mathrm{constant}$

The answer is:

$\frac{x \left(2 x y \sin{\left(2 y \right)} - x \cos{\left(2 y \right)} + x - 16\right)}{4}+ \mathrm{constant}$

/

$$\int \left(x y \sin{\left(2 y \right)} + x \sin^{2}{\left(y \right)} - 4\right)\, dx = C + \frac{x^{2} y \sin{\left(2 y \right)}}{2} + \frac{x^{2} \sin^{2}{\left(y \right)}}{2} - 4 x$$
