I know this is sort of a simple idea but many times simple things get glossed over and can leave students with a weak understanding of foundational knowledge. THANK YOU!

Hi, from India. Prepping for IIT-JEE, and Well explained👏👏👏. Wrt question solving and application, but lacks roots of concepts and conceptual understanding.

So the odd extension of an odd function is the function and the even extension of an even function is the function. Nice.
