Integral((4*x)*exp(x^2), (x, 0, 1))
Detail solution
  1. Let u=x2u = x^{2}.

    Then let du=2xdxdu = 2 x dx and substitute 2du2 du:

    2eudu\int 2 e^{u}\, du

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

      False\text{False}

      1. The integral of the exponential function is itself.

        eudu=eu\int e^{u}\, du = e^{u}

      So, the result is: 2eu2 e^{u}

    Now substitute uu back in:

    2ex22 e^{x^{2}}

  2. Add the constant of integration:

    2ex2+constant2 e^{x^{2}}+ \mathrm{constant}


The answer is:

2ex2+constant2 e^{x^{2}}+ \mathrm{constant}
