1 / | | x + 2 | 2 dx | / 0
Integral(2^(x + 2), (x, 0, 1))
There are multiple ways to do this integral.
Let .
Then let and substitute :
The integral of an exponential function is itself divided by the natural logarithm of the base.
Now substitute back in:
Rewrite the integrand:
The integral of a constant times a function is the constant times the integral of the function:
The integral of an exponential function is itself divided by the natural logarithm of the base.
So, the result is:
Now simplify:
Add the constant of integration:
The answer is:
/ | x + 2 | x + 2 2 | 2 dx = C + ------ | log(2) /
4 ------ log(2)
=
4 ------ log(2)
