NCERT Class 12 Maths · Chapter 9 Differential Equations · Exercise 9.1 Question 1
Determine order and degree of y⁽⁴⁾+sin(y‴)=0.
💡 Concept Hints
- Identify the domain and the inner and outer functions, or the relevant one-sided limits.
- Apply the appropriate differentiation or limit rule, keep all chain factors, and check exceptional points.
✅ Step-by-Step Solution
Final Answer: Order 4; degree not defined.
- The highest derivative appearing is of order 4.
- A trigonometric function of a derivative prevents polynomial dependence on derivatives, so degree is undefined.
