hey guys.

i am having sooo many troubles using ti89 pls pls help!

how do you convert the answers in exact values from the eulert programme into decimals without having to retype them in the homescreen?

[monokekie]

and and... how do you transfer what you typed in Y1 into the column at the bottom of the homescreen?

[monokekie]

also, how do you draw an elipse with a graphics calculator?

Set calc as approx mode and then run the program.

F4, define, y1(x) = [insert your equation]

also, how do you draw an elipse with a graphics calculator?

Solve for y, you will get a positive and negative half

then do define y1(x) = [positive half]

y2(x) = [negative half]

Green diamond F3.

tkx!!

and and... how do you transfer what you typed in Y1 into the column at the bottom of the homescreen?

F4, define, y1(x) = [insert your equation]

ohh i see, that's how you type into Y1 from homescreen...

so how do you transfer what you typed in "Y="  to homescreen?

[TrueTears]

I don't think you can, but I may be wrong.

[monokekie]

ok. lol

and...

how to get solid of revolutions with TI-89 without doing it manually with the antidifferential equation???(seeking an express way lol)

highlight it and copy and paste

Though im not a methods student (sorry for coming into this thread LOL), with further we also use the TI-nspire (different model to you though i think), and its ridiculous, our textbook is old, and has sooo many examples of using a calcultor on stuff in the chapter which saves valuable time, BUT IT SUES THE OLD CALCULATORS AS AN EXAMPLE!!! It hasn't been updated . I brought a book specifically about my calculator on how to use it.....only sueful thing (pffty), is how to create a scatter plot, which was COMMON SENSE, the rest is all about graphs and stuff which seems more for methods

*sigh*
