Integral(x^2*x^3/2 + 1*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:

      x2x32dx=x2x3dx2\int \frac{x^{2} x^{3}}{2}\, dx = \frac{\int x^{2} x^{3}\, dx}{2}

      1. There are multiple ways to do this integral.

        Method #1

        1. Let u=x2u = x^{2}.

          Then let du=2xdxdu = 2 x dx and substitute du2\frac{du}{2}:

          u24du\int \frac{u^{2}}{4}\, du

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

            u22du=u2du2\int \frac{u^{2}}{2}\, du = \frac{\int u^{2}\, du}{2}

            1. The integral of unu^{n} is un+1n+1\frac{u^{n + 1}}{n + 1} when n1n \neq -1:

              u2du=u33\int u^{2}\, du = \frac{u^{3}}{3}

            So, the result is: u36\frac{u^{3}}{6}

          Now substitute uu back in:

          x66\frac{x^{6}}{6}

        Method #2

        1. Let u=x3u = x^{3}.

          Then let du=3x2dxdu = 3 x^{2} dx and substitute du3\frac{du}{3}:

          u9du\int \frac{u}{9}\, du

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

            u3du=udu3\int \frac{u}{3}\, du = \frac{\int u\, du}{3}

            1. The integral of unu^{n} is un+1n+1\frac{u^{n + 1}}{n + 1} when n1n \neq -1:

              udu=u22\int u\, du = \frac{u^{2}}{2}

            So, the result is: u26\frac{u^{2}}{6}

          Now substitute uu back in:

          x66\frac{x^{6}}{6}

      So, the result is: x612\frac{x^{6}}{12}

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

      11dx=x\int 1 \cdot 1\, dx = x

    The result is: x612+x\frac{x^{6}}{12} + x

  2. Add the constant of integration:

    x612+x+constant\frac{x^{6}}{12} + x+ \mathrm{constant}


The answer is:

x612+x+constant\frac{x^{6}}{12} + x+ \mathrm{constant}
