∫01(x+7) dx\int\limits_{0}^{1} \left(x + 7\right)\, dx 
Integral(x + 7, (x, 0, 1))
Detail solution

  1. Integrate term-by-term:

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

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

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

      ∫7 dx=7x\int 7\, dx = 7 x

    The result is: x22+7x\frac{x^{2}}{2} + 7 x

  2. Now simplify:

    x(x+14)2\frac{x \left(x + 14\right)}{2}

  3. Add the constant of integration:

    x(x+14)2+constant\frac{x \left(x + 14\right)}{2}+ \mathrm{constant}

The answer is:

x(x+14)2+constant\frac{x \left(x + 14\right)}{2}+ \mathrm{constant}
