Q.

Which of the following is Hyperbola equation?

A. y2 + x2/b2 = 1
B. x2= 1ay
C. x2 /a2 – y2/b2 = 1
D. x2 + y2 = 1
Answer» C. x2 /a2 – y2/b2 = 1
Explanation: the equation x2 + y2 = 1 gives a circle; if the x2 and y2 have same co- efficient then the equation gives circles. the equation x2= 1ay gives a parabola. the equation y2 + x2/b2 = 1 gives an ellipse.
