AP EAMCET · Maths · Differential Equations
Order of the differential equation of the family of all concentric circles centered at \((h, k)\) is
- A \(1\)
- B \(2\)
- C \(3\)
- D \(4\)
Answer & Solution
Correct Answer
(A) \(1\)
Step-by-step Solution
Detailed explanation
The equation of the family of all concentric circles centred at \((h, k)\) is \[ (x-h)^2+(y-k)^2=r^2 \] \(h\) and \(k\) are given so, the above equation has only one parameter. \(\therefore\) Order of the differential equation \(=1\)
