Sketch and Find the area of the region determined by the intersections of the curves.
y= (2/(x2+1)), y=(absolute value of) x
I do not know how to proceed. The book I am using is of no help. Perhaps a push in the right direction is in order?
That's not entirely correct. You need to split it into two separate integrals because the function on the right side is x and the function on the left side is -x.
Technically the below is correct:
But that's not what you did - you dropped the absolute value.
