∫01(x3+4x) dx\int\limits_{0}^{1} \left(x^{3} + 4 x\right)\, dx 
Integral(x^3 + 4*x, (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:

      ∫x3 dx=x44\int x^{3}\, dx = \frac{x^{4}}{4}

    1. The integral of a constant times a function is the constant times the integral of the function:

      ∫4x dx=4∫x dx\int 4 x\, dx = 4 \int x\, dx

      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}

      So, the result is: 2x22 x^{2}

    The result is: x44+2x2\frac{x^{4}}{4} + 2 x^{2}

  2. Now simplify:

    x2(x2+8)4\frac{x^{2} \left(x^{2} + 8\right)}{4}

  3. Add the constant of integration:

    x2(x2+8)4+constant\frac{x^{2} \left(x^{2} + 8\right)}{4}+ \mathrm{constant}

The answer is:

x2(x2+8)4+constant\frac{x^{2} \left(x^{2} + 8\right)}{4}+ \mathrm{constant}
