I need to draw a parabola or graph the movement of an object in Turing. I am having a bit of trouble as I can only draw 1 kind of parabola and it doesn't seem to want to be altered to the numbers specified.

showing your code would help with questions like that, so that someone can point out where you're having problems

var setoff := 400 var y := 0 var a := 2 var b := 2 var c := 50 for x : 300 .. 300 y := round (a * (x + b) ** 2 + c) * 1 drawfilloval (x + 100, y + setoff, 1, 1, 5) end for ^^^ this is really what I had in mind and THX for your help Homer. its just that the value for setoff changes the size of my parabola.

you guys should find two points (well... one point and keep previous in another variable) and draw a line between two points instead. Then the graph would look like a complete curve, not a bunch of scatered dots

THx that makes alot of scence. Finding one point at a time is so easy and plus it'll be more original than some stuff other people in my class will graph
