Integral(sqrt(2*x - 1), (x, 0, 5))
Detail solution
  1. Let u=2x1u = 2 x - 1.

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

    u2du\int \frac{\sqrt{u}}{2}\, du

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

      udu=udu2\int \sqrt{u}\, du = \frac{\int \sqrt{u}\, du}{2}

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

        udu=2u323\int \sqrt{u}\, du = \frac{2 u^{\frac{3}{2}}}{3}

      So, the result is: u323\frac{u^{\frac{3}{2}}}{3}

    Now substitute uu back in:

    (2x1)323\frac{\left(2 x - 1\right)^{\frac{3}{2}}}{3}

  2. Now simplify:

    (2x1)323\frac{\left(2 x - 1\right)^{\frac{3}{2}}}{3}

  3. Add the constant of integration:

    (2x1)323+constant\frac{\left(2 x - 1\right)^{\frac{3}{2}}}{3}+ \mathrm{constant}


The answer is:

(2x1)323+constant\frac{\left(2 x - 1\right)^{\frac{3}{2}}}{3}+ \mathrm{constant}
