I get this is kind of an overdone question, but I still don’t really understand what it is. I think of math visually, and for some reason, I just can’t really get an idea of what sin and cosine “look like,” just that they are ratios.
Thanks!

Although trig is supposedly the study of triangles, I think the unit circle picture is more intuitive for beginners. Basically, (cos(theta), sin(theta)) are the coordinates for the points of a circle.
