1 / | | 1 | 4*1*------- dx | 3*x + 2 | / 0
Integral(4*1/(3*x + 2), (x, 0, 1))
The integral of a constant times a function is the constant times the integral of the function:
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 .
So, the result is:
Now substitute back in:
So, the result is:
Now simplify:
Add the constant of integration:
The answer is:
/ | | 1 4*log(3*x + 2) | 4*1*------- dx = C + -------------- | 3*x + 2 3 | /
4*log(2) 4*log(5)
- -------- + --------
3 3
=
4*log(2) 4*log(5)
- -------- + --------
3 3
