What is the order of the differential equation of all ellipses whose axes are along the coordinate axes?

Options

  1. A1
  2. B2
  3. C3
  4. D4

Correct answer

B. 2

Step-by-step solution

The general equation of all ellipses whose axes are along the coordinate axes, x^2 a^2 + y^2 b^2 =1 The above equation has two arbitary constants, so the differential equation will have order 2 .
