sin(x)cos(y)dy\int\limits_{-\infty}^{\infty} \sin{\left(x \right)} \cos{\left(y \right)}\, dy
Integral(sin(x)*cos(y), (y, -oo, oo))
Detail solution
  1. The integral of a constant times a function is the constant times the integral of the function:

    sin(x)cos(y)dy=sin(x)cos(y)dy\int \sin{\left(x \right)} \cos{\left(y \right)}\, dy = \sin{\left(x \right)} \int \cos{\left(y \right)}\, dy

    1. The integral of cosine is sine:

      cos(y)dy=sin(y)\int \cos{\left(y \right)}\, dy = \sin{\left(y \right)}

    So, the result is: sin(x)sin(y)\sin{\left(x \right)} \sin{\left(y \right)}

  2. Add the constant of integration:

    sin(x)sin(y)+constant\sin{\left(x \right)} \sin{\left(y \right)}+ \mathrm{constant}


The answer is:

sin(x)sin(y)+constant\sin{\left(x \right)} \sin{\left(y \right)}+ \mathrm{constant}
