JEE MAIN - Mathematics Bengali (2022 - 27th July Morning Shift - No. 8)
ধরি $$I = \int_{\pi /4}^{\pi /3} {\left( {{{8\sin x - \sin 2x} \over x}} \right)dx} $$ । তবে নীচের কোনটি সত্য?
$${\pi \over 2} < I < {{3\pi } \over 4}$$
$${\pi \over 5} < I < {{5\pi } \over {12}}$$
$${{5\pi } \over {12}} < I < {{\sqrt 2 } \over 3}\pi $$
$${{3\pi } \over 4} < I < \pi $$
