      so f is a function that yield a value between the ribbons bounded by cos and sin scaled by r, which is just a linear line, and then you define the axis t itself as a mapping that multiplies 3/2 to everything.

      I give up, what is it? It sounds like a single point on a graph, but what is it solving

        It’s a parametric plot of an object that goes from straight down at 0.5 units, then expands to 3 units in a 45° upright angle.

        originally I parameterized r as r(t) = (1-t)lenght_0 + t * lenght_1, but then I subbed t in because it doesn’t actually start at zero, which made it ugly

        f is a curve

        [cos(t), sin(t)]

        this is a vector that on it’s own would just create a circle/arc, r deforms the arc.
