∫01(x2+4) dx\int\limits_{0}^{1} \left(x^{2} + 4\right)\, dx 
Integral(x^2 + 4, (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:

      ∫x2 dx=x33\int x^{2}\, dx = \frac{x^{3}}{3}

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

      ∫4 dx=4x\int 4\, dx = 4 x

    The result is: x33+4x\frac{x^{3}}{3} + 4 x

  2. Now simplify:

    x(x2+12)3\frac{x \left(x^{2} + 12\right)}{3}

  3. Add the constant of integration:

    x(x2+12)3+constant\frac{x \left(x^{2} + 12\right)}{3}+ \mathrm{constant}

The answer is:

x(x2+12)3+constant\frac{x \left(x^{2} + 12\right)}{3}+ \mathrm{constant}
