Update:
I’ve finally had the time to make some changes to the trajectory calculator/simulator. There are two big changes.
First change:
I’ve added a green dot to the graph, which marks the location of the shooter. Position_X, Position_Y, and height are in relation to the origin of the graph!
Second change:
With some inspiration from other Desmos trajectory graphs which account for possible error (such as this one and this one from 2022), I’ve also included two sliders which you can play around with to introduce possible margins of error to the initial launch angle and launch velocity!
Thank you all so much for all the helpful comments and feedback. I’ve linked the new and improved Desmos trajectory calculator below :). Any further comments/suggestions are always welcome!
