Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

sorry I changed the axis. doubt
on changing axis , answer should be same . no effect of axis
please answer what is asked for, kindly revisit my doubt
on changing direction , it will be from f(y) =-√(1-y^2) to √(1-y^2)
what is g(y) and m?
please write on paper no, it's clear there.
if we change the axes , then ..
Remember - here we are not finding simple volume so that we can find it directly or in any way . Its surface of revolution , here we have to find using standard formula of volume .
you are integrating along the y axis(i.e.dy) but the bounds of integration is along the z axis, isn't that wron g?
we use this formula I know, but It is hard for me to understand what to put in m, fx , & gx. please explain that in a bit detail.
this formula will not be used here . In your formula revolution axis is different
then what formula is used?
replace x by y (I.e alternate to this )
what should be m?
m=0
how do you know m=0?
