This is your function?
Does it intersect the x-axis on the interval ?
Let R be the region bounded by the graph of y =x ex cos(x), the origin and the line x = 2.
Sketch the graph of R. Show the scale.
Find the area of region R.
So far, I've tried to sketch the region and this is all I have. I'm not even sure if it's right.
Look at the link below, please.
