Question

The order of the differential equation of all circles whose radius is 4, is ______.

Options

• 1

• 2

• 3

• 4

Answer 1

The order of the differential equation of all circles whose radius is 4, is 2.

Explanation:

Let equation of all circles having centre (a, b) and given radius is 4, is

(x - a)² + (y - b)² = 4

Here, number of arbitrary constant in two (a, b) so Its order is 2.
