JEE Mains · Maths · STD 12 - 5. continuity and differentiation

माना \(a \in \mathbb{Z}\) है तथा \([t]\) महत्तम पूर्णांक \(\leq t\) है। तब उन बिन्दुओं, जहाँ \(\mathrm{f}(\mathrm{x})=[\mathrm{a}+13 \sin \mathrm{x}], \mathrm{x} \in(0, \pi)\) अवकलनीय नहीं है, की संख्या है________

  1. A \(24\)
  2. B \(23\)
  3. C \(22\)
  4. D \(25\)
Verified Solution

Answer & Solution

Correct Answer

(D) \(25\)

Step-by-step Solution

Detailed explanation

\(f(x)=[a+13 \sin x], x \in(0, \pi)\) For \([n \sin x ]\); Total number of non differentiable points are \(=2 n-1\) for \(x \in(0, \pi)\) So number of non differentiable points for \([13 \sin x] \Rightarrow 25\) Points
