Q17 of 462 Page 22

Mark the correct alternative in each of the following:

The differential equation of the ellipse is



Since the equation has 2 constants so we differentiate twice,


Differentiating w.r.t x




--(1)


Again, differentiating w.r.t x


--(2)


Substitute value of (2) in (1) we get,



Dividing both sides by y.y’ we get,
