I will post pictures in a couple hours, currently I do not have access to them.
I've been experimenting with the basic parametric graphing mode and am trying to write an equation that sets the x value back to the beginning when it reaches an edge.
Specifically, I am using this to try and graph a rudimentary satellite ground track.
Currently, I have it written so whenever it completes a period it will subtract the length of the whole window, resetting the x value to -180.
It is written as such:
X1T=((2CT/B)-(2C(int(T/B))-C
C = 180 (the distance from the origin to the edge)
B = the period
Essentially, the graph starts at x=-180 and whenever (T/B) returns an integer value (meaning enough time has passed to cover 2C, the entire window) it will subtract that integer value multiplied by the window and reset to x=-180.
This equation generally works, it gets the job done, but is there a better way to do this? Possibly a more general way with logic or combining equations? Perhaps a way that could be used to generate a flat torus window?
However, my biggest problem with this equation is that it produces annoying lines whenever the x position resets kind of like asymptotes in function mode when detectAsymptotes is disabled. I'm struggling to find a good way to fix this. My current solution is to graph with a dotted line but that requires a small and slow Tstep to look presentable.
TLDR: How can I prevent lines being graphed in parametric mode when graphing an equation that suddenly jumps to another position?

While I don't know of a solution for any calc, what calculator is this for?
