Sup, I'm having a lot trouble solving for Y. could someone help me? The link below leads to the online calculator Desmos programmed to display their generic elliptical using their default elliptical equation. Could you solve their equation for me? The condition is that you only know the value of X and A but not Y. I really want to create this new graphic effect for my website called "Fire Egg" and I'm going to need math to do it. first I'm going to need to restructure the ellipse equation to be in standard form "y = x + 1". Then I'll be able to provide x values and easily have a y coordinate for the on screen particles I'll be making. https://www.desmos.com/calculator/42lngkxil6

It's done this thread is complete, it took a minute but I got it. The rotating elliptical equation is complete. All I need to do to get this thing running is give an X, width, and height and it will spit out a Y value for particle placement. All I need to do now is pray to the programming gods for this to not run slow.
