how to calculate distance between origin and furthest point on graph?
Hello! I am new on this forum so forgive me if I don't respect all "rules" or if someone answered already this question.
If you take a look at the image, I just want to know how to calculate the distance between origin and the furthest dot on the graph.
var('t') ff = (exp(cos(t)) - 2*cos(4*t) + sin(t/12)^5) parametric_plot((ff*cos(t),ff*sin(t)), (t,0,2*pi) , fill=True, fillcolor='orange', figsize=[3,3])
