1 / | | 3 _________ | \/ 2*x + 1 | ----------- dx | 2*x + 1 | / 0
Integral((2*x + 1)^(1/3)/(2*x + 1), (x, 0, 1))
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 is when :
So, the result is:
Now substitute back in:
Now simplify:
Add the constant of integration:
The answer is:
/ | | 3 _________ 3 _________ | \/ 2*x + 1 3*\/ 2*x + 1 | ----------- dx = C + ------------- | 2*x + 1 2 | /
3 ___ 3 3*\/ 3 - - + ------- 2 2
=
3 ___ 3 3*\/ 3 - - + ------- 2 2
-3/2 + 3*3^(1/3)/2
Use the examples entering the upper and lower limits of integration.
