Homework Statement
integral of x|x|dx.. [-1,1]
The Attempt at a Solution
when graphing it, it is even (looks like the cubic function) and would be 0... but I am having problems convincing myself of this. i checked it out using my calculator, and it just gives back x|x|.. i know if you do the integral of abs x you would split it up into positive and negative parts and all that.. but this is obviously different since it goes below y=0...
