Is there a specific part you're having difficulties with?  Or not sure how to begin?

anonymous · Answer

i didn't get this question at all from beginning.
as far as i think first we have to make graph of 2tan(x/4) after that i  don't know what to do.

accessdenied · Answer

A graph of 2tan (x/4) will be useful, yes.

accessdenied · Answer

Along with our other two lines x=0 and  x= pi
The reasoning is mainly to see what is going on with the function and eventually set up the solid of revolution integration.

Have you already got that drawn?

the graph?

accessdenied · Answer

Yeah.

i think so let me show you how i graphed.|dw:1395368021106:dw|
