JEE Mains · Maths · STD 12 - 7.2 definite integral

माना \(\displaystyle\int_{-2}^{2} (|\sin x| + [x \sin x])\,dx = 2(3 - \cos 2) + \beta\), जहाँ \([\cdot]\) महत्तम पूर्णांक फलन है। तो \(\beta \sin\left(\dfrac{\beta}{2}\right)\) बराबर है:

  1. A \(1\)
  2. B \(2\)
  3. C \(4\)
  4. D \(8\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(2\)

Step-by-step Solution

Detailed explanation

माना \(I = \displaystyle\int_{-2}^{2} \left(|\sin x| + [x \sin x]\right) dx = I_1 + I_2\), जहाँ \(I_1 = \displaystyle\int_{-2}^{2} |\sin x|\, dx\) तथा \(I_2 = \displaystyle\int_{-2}^{2} [x \sin x]\, dx\) है। \(I_1\) का मान ज्ञात करना: चूँकि \(|\sin x|\) एक सम फलन है,…
