Looks Impossible… But Collapses Beautifully! | JEE Advanced Maths

Looks Impossible… But Collapses Beautifully! | JEE Advanced Maths In today’s Factorial’s Question of the Day, we discuss a beautiful JEE Advanced level integral that looks complicated but unlocks instantly once you recognise the hidden structure. Before solving the main problem, we build the required prerequisite idea. This is exactly how advanced problems should be approached: understand the mechanism, not memorise tricks. ⸻ ✅ Question Discussed Let f(x,n)=\int \frac{x^2+n(n-1)}{(x\sin x+n\cos x)^2}\,dx, where n\in\mathbb{N}. It is given that f(0,n)=0 \quad \text{for all } n\in\mathbb{N}. Find the numerical value of (12+\pi)\,f\!\left(\frac{\pi}{4},\,3\right). ⸻ This problem is a perfect example of how JEE Advanced tests insight, not expansion. If you enjoyed this, you must follow the entire Factorial’s Question of the Day series to sharpen your mathematical vision daily. 📌 Join our Telegram for notes & discussion: https://t.me/academyfactorial #FactorialsQuestionOfTheDay #JEEAdvanced #JEEMaths #DefiniteIntegration #IITJEE #JEE2026 #JEEMains2026 #JEEMaths2026 #MathsForJEE #FactorialAcademy #ConceptualMaths #JEEPreparation
