| I would use something that corresponds with the keys being pressed, though i never really thought hard about doing it in basic, assembly is they way to go.... It would take a person that knows they're shit about basic to do that. If i remember correctly there was someone that had done a 3D rotation in basic..... I don't remember where it was, i'll keep my eye out for it... |

Yeah, that's easy. Sin( and Cos( will give you the X and Y coordinates for something that is 1 away from a point. All you have to do is give it an angle. So if you want to find out the coordinates for 90 degrees, use these as X and Y:
sin(90)->X
cos(90)->Y
-> means the STO key, just above the ON button. If you want to find out the coordinates for an object 5 away from a point at 90 degrees, just do this:
5sin(90)->X
5cos(90)->Y
And if you want the coordinates for an object 5 away from the point (49,2 , then do this:
49+5sin(90)->X
28+5cos(90)->Y
Etc. Of course, you can use variables in place of any of those numbers. Hopefully this helps you. If you need more specifics, let me know. And if anyone sees any mistakes I made please let me know.
And welcome to UTI!

You can only give it an angle between 0 and 360 if your calc is in degrees mode, if it's in radian mode you need to convert it like htis:
degrees = 180*radians |

Hm.. Im using this when I usually convert to degrees
degrees = (180 / pi) * radians |

| radians being 0.5*pi for example. |

whoa, I didn't realize angles were so easy!
I was trying to think up some mathmatical way to do them  |

Hehe, yeah the basics are easy. But just wait for trig, then you'll see.

| This is trig. Also, you could try using the polar > rectangular conversions: P>Rx( and P>Ry( to do the same thing. Don't know why though, sin( and cos( are faster and smaller. |

That helped. 
Is it short for something? Triginometrics? |

Most people call it "trigonometry".
And for FFR:
logs -> logarithms
calc -> calculus
quad -> quadratic
et al.

Well, most over here would call it Trigonometry. Trigonometrics makes more sense though... |
