∫01ex+2 dx\int\limits_{0}^{1} e^{x + 2}\, dx 
Integral(E^(x + 2), (x, 0, 1))
Detail solution

  1. There are multiple ways to do this integral.

    Method #1

    1. Let u=x+2u = x + 2.

      Then let du=dxdu = dx and substitute dudu:

      ∫eu du\int e^{u}\, du

      1. The integral of the exponential function is itself.

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

      Now substitute uu back in:

      ex+2e^{x + 2}

    Method #2

    1. Rewrite the integrand:

      ex+2=e2exe^{x + 2} = e^{2} e^{x}

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

      ∫e2ex dx=e2∫ex dx\int e^{2} e^{x}\, dx = e^{2} \int e^{x}\, dx

      1. The integral of the exponential function is itself.

        ∫ex dx=ex\int e^{x}\, dx = e^{x}

      So, the result is: e2exe^{2} e^{x}

  2. Now simplify:

    ex+2e^{x + 2}

  3. Add the constant of integration:

    ex+2+constante^{x + 2}+ \mathrm{constant}

The answer is:

ex+2+constante^{x + 2}+ \mathrm{constant}
