1 / | | _________ | \/ 3*x - 1 | ----------- dx | 3 | / 0
Integral(sqrt(3*x - 1)/3, (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 when :
So, the result is:
Now substitute back in:
So, the result is:
Now simplify:
Add the constant of integration:
The answer is:
