0 / | | (3*x - 1)*(3*x - 1) dx | / 1
Integral((3*x - 1)*(3*x - 1), (x, 1, 0))
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 is when :
So, the result is:
Now substitute back in:
Rewrite the integrand:
Integrate term-by-term:
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:
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:
The integral of a constant is the constant times the variable of integration:
The result is:
Now simplify:
Add the constant of integration:
The answer is:
/ 3 | (3*x - 1) | (3*x - 1)*(3*x - 1) dx = C + ---------- | 9 /
