A significant portion of the lecture is dedicated to the Differentiation Operator, where the Atal Sir proves that while the eigenvalue is unique ($\lambda = 0$), the corresponding eigenvectors (constant polynomials) are uncountable. The session also emphasizes careful reading of exam questions—specifically identifying "Incorrect" statements, which is a common trap in CSIR NET. Atal Sir concludes by demonstrating how to handle functional inequalities by substituting variables to create matching bounds for a "Squeeze Play" solution. ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ 🔗 Important Links: 🌍 Visit our Website: https://ifasonline.com 📞 Contact for Queries: 9172266888 📲 WhatsApp: https: https://whatsapp.com/channel/0029VbCV... 🔥 Qualification Prediction (Free Tool): https://ifasonline.com/QualificationP... 📘 Get Detailed Free Counselling: https://ifasonline.com/csir-net/mathe... ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ Download IFAS: 👇 📲Android: https://play.google.com/store/apps/de... 📲 Ios: https://apps.apple.com/us/app/ifas/id... ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ CSIR NET Mathematical Science Live & Recorded Course – https://ifasonline.com/csir-net/mathe...
