Integral(E^(-x^4) + 5*x^3*1, (x, 0, 1))
Detail solution
  1. Integrate term-by-term:

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

      5x31dx=5x3dx\int 5 x^{3} \cdot 1\, dx = 5 \int x^{3}\, dx

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

        x3dx=x44\int x^{3}\, dx = \frac{x^{4}}{4}

      So, the result is: 5x44\frac{5 x^{4}}{4}

    1. Don't know the steps in finding this integral.

      But the integral is

      Γ(14)γ(14,x4)16Γ(54)\frac{\Gamma\left(\frac{1}{4}\right) \gamma\left(\frac{1}{4}, x^{4}\right)}{16 \Gamma\left(\frac{5}{4}\right)}

    The result is: 5x44+Γ(14)γ(14,x4)16Γ(54)\frac{5 x^{4}}{4} + \frac{\Gamma\left(\frac{1}{4}\right) \gamma\left(\frac{1}{4}, x^{4}\right)}{16 \Gamma\left(\frac{5}{4}\right)}

  2. Now simplify:

    5x44+γ(14,x4)4\frac{5 x^{4}}{4} + \frac{\gamma\left(\frac{1}{4}, x^{4}\right)}{4}

  3. Add the constant of integration:

    5x44+γ(14,x4)4+constant\frac{5 x^{4}}{4} + \frac{\gamma\left(\frac{1}{4}, x^{4}\right)}{4}+ \mathrm{constant}


The answer is:

5x44+γ(14,x4)4+constant\frac{5 x^{4}}{4} + \frac{\gamma\left(\frac{1}{4}, x^{4}\right)}{4}+ \mathrm{constant}
