જો સંકર સંખ્યા \((1-\cos \theta+2 i \sin \theta)^{-1}\) નો \(\theta \in(0, \pi)\) માટે વાસ્તવિક ભાગ  \(\frac{1}{5}\) હોય તો \(\int_{0}^{\theta} \sin x \,d x\) ની કિમંત મેળવો.

  1. A \(2\)
  2. B \(-1\)
  3. C \(0\)
  4. D \(1\)
Verified Solution

Answer & Solution

Correct Answer

(D) \(1\)

Step-by-step Solution

Detailed explanation

\(z=\frac{1}{1-\cos \theta+2 i \sin \theta}\) \(=\frac{2 \sin ^{2} \frac{\theta}{2}-2 i \sin \theta}{(1-\cos \theta)^{2}+4 \sin ^{2} \theta}\)…
