what does the "t" mean in parametrics.. its suppose to be the parameter but what's that??

Basically, its just a variable that can be changed. Changing its value effects the values of other things that 't' is a parameter for.

Most people like to think of it as similar to 'time'. 'Time' isnt effected by any other parameters, it simply moves along effecting other variables, such as x and y coordinates in projectile motion.

^ i think you should be careful when using "time" as an analogy acmilan , and when you say "time isn't affected by any other parameters"... maybe by "time" you mean our measurement of time... rather than time itself.
time is unchanging only in the sense of our definition of the passing of time - where the unit 'second' is defined as a constant interval of time, and where every second is of equal lengths.
this is, however, different from 'dimensional time' whose geometry is affected by many things...

but i'm sure kadlil will know what you mean

damnit I was waiting for that

But yeah i do understand its not exactly the same, its just the way most people seem to learn it the easiest.

hehe... yea i understand that you would know about that, but just thought i'd get on your nerves by pointing it out
no but i'm sure kadlil would know what you're saying too though
