Understanding math through the act of drawing function plots is another level of satisfaction.
I could write a short script for the calculations of these parametric equations or choose between hundreds of other faster digital options, but I prefer the old-school method of pen and paper - also helps with my poor working memory - so, "two flies catched with one trap", as this idiom goes...
I love 3-dimensional function plots!
(Also: I often choose weird/unconventional ways to portray the concepts, often as result of spontaneous playing with patterns and accompanied occasional eureka-moments.)
