trebuchet simulator in turing

-----------------------------------

ok so i am trying to make a trebuchet simulator with Turing . i have attached a copy of what i have done so far however i need help of getting the graphic and for it to loop.

there are 3 error in it 
1. it wont let me put g as a constant 
2. it wont let me close brackets
3. it wont let me use sine and cosine function

plz help

okay first of all, your variable have to be real numbers if you are dividing and using sine or cosine

eg. var Mc,g,h,PE,e,KE,v,Mp,o,Vx,Vy,t,d : real

as opposed to what you have which is:var Mc,g,h,PE,e,KE,v,Mp,o,Vx,Vy,t,d : int

secondly, when you are using sine or cosine the syntax would be:Vx := v* cos (o)
Vy := v* sin (o)

instead of what you have which is:Vx := v*cos o
Vy := v*sin o


also, when you have:KE:= e*PE
thats not going to work because neither e nor PE have a value to them so the function wont happen

so when multiplying things in turing u have to keep space after *? btw e is 0.5J

you dont need a space but you need the () around the angle which in your case, is "o"

would Turing automatically turn my degrees into radians or is there a code for that?

You could use sind, cosd, and all the other trig functions that use degrees. Or you could write your own function to convert (its not very hard).
