Let the centre of circle be (h, k) and radius a, then its equation will be
(x - h) + (y - k)2 = a2
Since, there are two parameters h and k So, the differential equation is of order 2.
If a = and the angle between a and b is , then the area of the triangle formed by these two vectors as two sides is
