B ki 10th power nikaalni hai — ek matrix jismein sinθ aur cosθ dono hain. Dekhte hi lagta hai calculation ka pahaad khड़ा ho gaya hai. Actual mein iska jawaab bina ek bhi sinθ ya cosθ likhe nikal aata hai — B¹⁰ seedha A¹⁰ ban jaata hai. JEE Main 2025 ka yeh PYQ Advanced-level difficulty hai — do alag structural tricks ek saath use hote hain: orthogonal matrix ka property, aur triangular matrix ki power. Poori derivation is video mein, step by step, koi step skip nahi. 📌 Concept covered: Orthogonal Matrices (PPᵀ=I) + Triangular Matrix Powers (Class 12, Matrices) 📌 Difficulty: Hard — Advanced-level, but two clean shortcuts once spotted 📌 Ideal solve time: 5-6 minutes PYQ Decoded series ka hissa — real JEE PYQs jo dekhne mein monstrous lagte hain, ek NCERT concept se seedha khulte hain. 🔔 Subscribe for daily JEE Main + Advanced Maths, decoded PYQ-by-PYQ. #jeeadvanced #jeemains #iitjee #matrices #orthogonalmatrix #jeemaths #ncert #jee2027 #jeepreparation #mathsforjee #pyqdecoded #xerofinity #TriangularMatrix #JEEMotivation #studysmart
