I’m preparing for a summer precalculus course and it took me about a week to understand sine and cosine functions to a pretty good extent and now I’m learning tan and cotangent functions!
Hi, I’m not at this level yet but I’d like to tell you I’m so grateful for your videos, you’ve helped me so much with my math class and I love how you explain things, thank you so much!
He divided the period by 4 to get four points in between where the graph starts and ends for one cycle. It's just to graph it. Without the points in between you wouldn't be able to graph it accurately.
