Find the integral
f(x) = x^3 sqrt(x^2 + x^8 + 8) cox(x) dx
The Attempt at a Solution
I need help starting. It appears to be either integration by parts and/or substituion.
It does in this case. For your function f(-x)=(-f(x)), it's an odd function. What happens if you integrate an odd function over a symmetric interval around the origin?The problem wanted the function evaluated from -14 to 14. Does it make a difference if it is definitive or not? Is there a trick if it is definitive?
