Are there built in tools, (or any working software), for the hp prime, that will find parabola parameters such as: vertex, focus, directrix, and axis of symmetry?

For example: Provide an equation such as y=x^2+4*x-5, and find the above items.

Thanks for the clarification of your program usage! I d/l'd it and gave it a try, but I used the form Conics(y=x^2+4*x-5), not Conics(y-(x^2+4*x-5)); which returned an error. In the interest of time, I needed to move on.

[Suggestion]
A commented description field, perhaps at the top of the program, with a few examples of input/output format, might add value to your program.

Your program is very useful, and provides just the sort of information I was after. Thank you for sharing your effort!
