Learn about polymorphic functions and essential type classes including Eq, Ord, and Num in this 57-minute lecture from NPTEL-NOC IITM. Explore how polymorphism enables functions to work with multiple data types while maintaining type safety, and discover how type classes provide a structured way to define common operations across different types. Master the implementation and usage of fundamental type classes that form the backbone of functional programming, understanding how Eq enables equality comparisons, Ord provides ordering capabilities, and Num supports numeric operations across various data types.
