NCERT Class 12 Maths · Chapter 9 Differential Equations · Exercise 9.1 Question 5
Determine order and degree of y″=cos 3x+sin 3x.
💡 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 2; degree 1
- The highest derivative appearing is of order 2.
- The equation is polynomial in its derivatives; the highest-order derivative has exponent 1. The powers of lower derivatives do not determine the degree.
