I took this stupid quiz on finding the next number in the pattern, and at the end, it didn't tell me the right answers! the one that stumped me was: 73, 61, 56. 62, ? anyone know the answer?

or really using anything the ti-89 titanium is capable of graphing, not just parametrics.

does anyone have a really good method for writing out words or messages using parametric equations, or ...even better a program to do it for me?

alright thanks everyone! I'm not sure i understand yet, but I'll look into it a little bit more... maybe ask my math and physics teachers... it'll probably be easier to explain in person. :-) thanks, and goodnight.

I'm not sure I do understand what radius vector means... I assumed it meant a measurement which coupled the length of the radius with the direction it's rotation. "If I want to specify a vector for something moving at speed v away from the sun" Away from the sun? do you mean around the...

lol thanks, that makes a bit more sense... i think I'm in over my head here, though :-) So when you say expand or contract the radius vector... what do you mean? If you think its too hard to explain in terms i'll understand, i can wait till college :-) -thanks!

um... i still don't understand what it means.

so in an equation about a heavenly body revolving around another heavenly body, r^ basically says that it is defining the speed as 1 and the direction as around something else? what does "in the direction of the radius" mean?

I was watching some Public television at 2:30 AM (it's when all the best programming is on)... and they were doing this bit on old astronomers and the mathematics behind it... they didn't go into detail, and i understood everything that was spoken aloud... but they would flash equations in...

thanks...thats really cool, I left my ti-89 at school, but when i get it again, i'll plug that into it and see if it gives me e... that is really cool... one more question... why did you say Daniel at the very end of your post?

alright... so what is e? I'm doing all this fun stuff integrating and deriving things with e in them to find weird stuff... the homework isn't too bad... but what the heck is e? I know what number it stands for... but where do we get it from and what does it mean?

no, it isn't... then keep it there.

... brain washing did not get bush re-elected... if you wish that subject to be discussed, perhaps you should go into the politics sub-section.

DUH. *slaps self on forhead* ... heh... forgot a single step and it screwed me up (of course). Thanks.

All the children I know whose parents don't spank them turned into whiny, feminine adults (yes... even the men) ...
