The parametric curves on the parametric curve feature are so big, how can I shrink them?

I've been using this https://cad.onshape.com/documents/57a62df8e4b03de4c9fcf154/w/f6d71f3d862b522902efcd68/e/80a61feafb79991a92090fba#_ga=2.55591275.1385095980.1659474998-869664523.1659106986
for a while and whenever I plot a function, it is so big and unusable. I wonder how I can make it smaller.

you could probably use a scalar number in the equation itself. If not, you could scale the curve after creation with the Transform tool.

Hi @vincent_li240. I wrote the FS in question. Like Evan suggests, the feature will spit out however large a curve is necessary to satisfy the equation inputs. If you have a specific size in mind, one way to figure out the proper equation is to keep in mind the limits of the parameter #t. It can be changed, but by default #t goes from 0 to 1. So just try to think ahead and see what the output would be for #t=0 and #t=1. If you know there will be a maximum or minimum at some other value of #t, then you can use that as a guide. Not to be dismissive, but it's just math. Barring some bug in the code (which is quite possible since I'm not perfect), you'll get out what you put in.

Also, if you can communicate what you're trying to achieve, I and plenty of other folks on the forum would be happy to help you tweak your equations.
