That was the moment. Cengage wasn't just a problem set. It was a . Arjun pointed at the coaching modules

That night, Arjun turned to a random page in by G. Tewani. Chapter: Application of Derivatives . Topic: Tangents and Normals . He chose a problem marked with the infamous red star (*) – the "advanced" level. That was the moment

He stared for an hour. Then, he re-read the theory in Cengage, not the solved problems.

Never rely solely on the slope form; it fails for vertical lines."
