in volumes of revolution (calculus) is there a difference between rotation about the y and x axis?
dy and dx
u need to use different splices
is that the only difference i write in the formula?
normally using disc method if you revolve around x-axis then integrate wrt x revolve around y-axis integrate wrt y
they are totally different because the equation changes
ok thanx do i check for the intersection points or do i just use the given interval
