JEE Mains · Maths · STD 12 - 7.2 definite integral

माना \(f:(-1,1) \rightarrow R\) एक संतत फलन है। यदि \(\int \limits_{0}^{\sin x} f( t ) dt =\frac{\sqrt{3}}{2} x\) है, तो \(f\left(\frac{\sqrt{3}}{2}\right)\) बराबर है

  1. A \(\frac{1}{2}\)
  2. B \(\frac{{\sqrt 3 }}{2}\)
  3. C \(\sqrt {\frac{3}{2}} \)
  4. D \(\sqrt 3 \)
Verified Solution

Answer & Solution

Correct Answer

(D) \(\sqrt 3 \)

Step-by-step Solution

Detailed explanation

Let \(f:\left( { - 1,1} \right) \to R\) be a continuous function Let \(\int\limits_0^{\sin x} {f\left( t \right)dt} = \frac{{\sqrt 3 }}{2}x\) \(f\left( {\sin x} \right).\frac{d}{{dx}}\left( {\sin x} \right) = \frac{{\sqrt 3 }}{2}\)…
