NCERT Class 12 Maths · Chapter 5 Continuity And Differentiability · Exercise 5.2 Question 3
Differentiate \(\sin{\left(a x + b \right)}\) with respect to x; on R.
💡 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: \(a \cos{\left(a x + b \right)}\)
- Work on R.
- Differentiate the outer function and multiply by the inner derivative: \(\frac{\partial}{\partial x} \sin{\left(a x + b \right)}\) = \(a \cos{\left(a x + b \right)}\).
- Combining the terms gives y′ = \(a \cos{\left(a x + b \right)}\).
