Integral(2*x + y, (y, 0, 2))
Detail solution
  1. Integrate term-by-term:

    1. The integral of a constant is the constant times the variable of integration:

      2xdy=2xy\int 2 x\, dy = 2 x y

    1. The integral of yny^{n} is yn+1n+1\frac{y^{n + 1}}{n + 1} when n1n \neq -1:

      ydy=y22\int y\, dy = \frac{y^{2}}{2}

    The result is: 2xy+y222 x y + \frac{y^{2}}{2}

  2. Now simplify:

    y(4x+y)2\frac{y \left(4 x + y\right)}{2}

  3. Add the constant of integration:

    y(4x+y)2+constant\frac{y \left(4 x + y\right)}{2}+ \mathrm{constant}


The answer is:

y(4x+y)2+constant\frac{y \left(4 x + y\right)}{2}+ \mathrm{constant}
