Description

This lecture covers the concepts of surjectivity, injectivity, and bijectivity in functions. It explains how a function is surjective if its range covers its codomain, injective if distinct inputs map to distinct outputs, and bijective if it is both surjective and injective. The lecture also discusses the inverse function and provides examples using trigonometric functions like sine, cosine, and tangent.
