aa line ba hyperbola can ellipse da line segment ea prtion o

a)a line

b)a hyperbola

c)an ellipse

d)a line segment

e)a prtion of a hyperbola

Solution

x = sec(theta) ; y = costheta

we know sectheta = 1/costheta

x*y = sec(theta)*costheta

xy = 1

y = 1/x   

It can be transformed into a hyperbola

Option e
