Integral(y*x, (x, 500, 625))
Detail solution
  1. The integral of a constant times a function is the constant times the integral of the function:

    xydx=yxdx\int x y\, dx = y \int x\, dx

    1. The integral of xnx^{n} is xn+1n+1\frac{x^{n + 1}}{n + 1} when n1n \neq -1:

      xdx=x22\int x\, dx = \frac{x^{2}}{2}

    So, the result is: x2y2\frac{x^{2} y}{2}

  2. Add the constant of integration:

    x2y2+constant\frac{x^{2} y}{2}+ \mathrm{constant}


The answer is:

x2y2+constant\frac{x^{2} y}{2}+ \mathrm{constant}
