Huhh First of all I'm sorry if this is the wrong question ( didn't know if this was considered pre cal. I have a gut feeling it is :P)
Let R be the region bounded by y=tan x, y=0 and x = Pi/4
Find the volume of the solid whose base is region R and whose cross-section is a square perpendicular to the x-axis
Huh well I don't know whether its cylindrical shell:
∫ab Pi(R)(Height)dx
or disk method
∫ab A(x) dx
I can't even figure out what the graphs look like. The wording is really confusing. I tried using a pyramid shape with a square base because it says the cross section is a square and using similar triangle ( I think its called like that...) but I couldn't get the equation for the formula.
