NCERT Class 12 · Ch 9 Exercise 9.2 · Q3
NCERT Class 12 Maths · Chapter 9 Differential Equations · Exercise 9.2 Question 3
Verify y=\(C + \cos{\left(x \right)}\) solves y′+sin x=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: Verified on the stated real domain.
- Differentiate the proposed function: y′=\(- \sin{\left(x \right)}\).
- Substitution into the equation leaves \(0\); hence it is satisfied.
