माना \(\quad S=\left\{t \in R: f(x)=|x-\pi| \cdot\left(e^{|x|}-1\right) \sin |x|\right.\) जो \(t\) पर अवकलनीय नहों है\(\}\), तो समुच्चय \(S\) बराबर है

  1. A \(\left\{ 0 \right\}\)
  2. B \(\left\{ \pi \right\}\)
  3. C \(\left\{ {0,\pi } \right\}\)
  4. D \(\emptyset \)
Verified Solution

Answer & Solution

Correct Answer

(D) \(\emptyset \)

Step-by-step Solution

Detailed explanation

\(\left( 4 \right)\,\,\,\,\,\,\,f\left( x \right) = \left| {x - \pi } \right|\left( {{e^{\left| x \right|}} - 1} \right)\sin \left| x \right|\) Check differentibility of \(f(x)\) at \(x = \pi \) and \(x=0\) at \(x = \pi :\)…
