x / | | x - 2 | ----- dx | 6 | / 1
Integral((x - 2)/6, (x, 1, x))
The integral of a constant times a function is the constant times the integral of the function:
Integrate term-by-term:
The integral of is when :
The integral of a constant is the constant times the variable of integration:
The result is:
So, the result is:
Now simplify:
Add the constant of integration:
The answer is:
/ | 2 | x - 2 x x | ----- dx = C - - + -- | 6 3 12 | /
2 1 x x - - - + -- 4 3 12
=
2 1 x x - - - + -- 4 3 12
1/4 - x/3 + x^2/12
