What are the order and degree of the differential equation ?
Answer and explanation
Correct answer: A. Order 2 and Degree not defined
- Step 1: The order of a differential equation is the order of the highest derivative present. Here, the highest derivative is , so order is 2.
- Step 2: Because the differential equation contains a transcendental function , it cannot be expressed as a polynomial equation in derivatives.
- Step 3: Hence, its degree is not defined.
Answer
Order 2 and Degree not defined.
Why not the others: Order 2 and Degree 3 ignores the non-polynomial term; Order 3 confuses power with order; and Order 4 confuses derivative power with order.
