Algebra of Continuous Functions

The video tutorial explores the concept of continuity in functions, focusing on the algebra of functions and how continuity applies to the sum, difference, product, and quotient of functions. It demonstrates that if two functions are continuous at a point, their sum, difference, product, and quotient (provided the denominator is not zero) are also continuous at that point. The tutorial further examines the continuity of rational and composite functions, using examples like sine and cosine functions to illustrate these principles.
