Sum of Triangular Numbers II (visual proof via cannonballs)

This is a short, animated visual proof showing how a formula for the sum of the first n triangular numbers (which themselves are sums of the first n integers) using a three dimensional stack of spheres (that look like cannonballs). #manim #math #mathvideo #mathshorts #sequences #triangles #animation #theorem #pww #proofwithoutwords #visualproof #proof #triangularnumbers #sums #pww​ #proofwithoutwords​ ​ #proof​ #algebra #finitesums #mathematics​ #mathvideo​ #mtbos Here is an alternate video for a related sum:    • Sum of Triangular Numbers I (visual proof)   If you like this video, please click "like" and consider subscribing and checking out my other videos.
