For a class project, I have been asked to find the volume of the area bounded by two functions, with cross sections of equilateral triangles.

The two functions in question are

y = xsinx

y = -xsinx ,

And I need to find the volume that would result if the cross sections were equilateral triangles.

The interval upon which I have to do this is [-2π, 2π].I am aware that I have to integrate an area function in order to obtain the volume, but I am confused about how to get an area function for this.

Can anyone help? Thanks!
