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!
