1 / | | 2*x + 3 | E dx | / 0
Integral(E^(2*x + 3), (x, 0, 1))
There are multiple ways to do this integral.
Let .
Then let and substitute :
The integral of a constant times a function is the constant times the integral of the function:
The integral of the exponential function is itself.
So, the result is:
Now substitute back in:
Rewrite the integrand:

/ | 2*x + 3 | 2*x + 3 e | E dx = C + -------- | 2 /
5 3 e e -- - -- 2 2
=
5 3 e e -- - -- 2 2
exp(5)/2 - exp(3)/2
