Q)
(chatquestion)...Ex. 9.
Find the equation of the cone with vertex at (2a, b, c)
and passing through the curve x+y² =4u² and z=0. Find b and e
if the cone also passes through the curve y=4a (z+a), x 0. Also
show that the cone is cut by the plane y=0 in two straight lines
and the angle 8 between them is given by tan 0=2.
