Total Posts: 35 | I just bought an 89 Titanium, and I wanna get started with using TI connect. I have a question concerning the USB cable...
When I connected the Titanium to the computer using the USB cable, the calc turned on when it was previously turned on. I would like to know if it is now running off of the battery power in the calculator itself, or USB power from the comp? |

It is still on the battery power. |

btw, in that first post, i meant to say, "...the calc turned on when it was previously turned OFF" ; oopsies on me :img29:
yeah, USB power. you know, like how mp3 players and thumb drives work? usb can provide a certain amount of voltage to the device it's connected to. :sunglasses2:

Edit | Well, the only reason I know that was because my batteries kinda dropped dead on my calc once when it was plugged in with a USB port, and it was updating the OS... |

and that's true Ally, i forgot about hubs that use their own adapter. u think if i connect the calc via an external hub (therefore more juice) then the calc will switch to usb power? |

another problem.. i sent tetris.89z to my calc, tried running it, and nothing happens. i entered "tetris()" in the entry line. what am i doing wrong?! |

Check the game's documentation/readme. You may need a kernel or something. |

every program i try to run, nothing happens. the first program i ran (eqman) ran fine, but then no others will work now. when i try to run them, it just pastes it into the history window and that's it.
since i ran EqMan, the calc is displaying 'eqman' in the lower-left corner of the screen all the time now. what is this, and does this have anything to do with my other programs not runnin? |

Total Posts: 2007 | That is probably an error that was caused by a malcoded assembly or C program (don't know which eqman is). Your best bets would either be to reset all your memory, or, if you dislike that idea, find a kernel that restores your system after a crash, i think there are a few nice ones here on calcgames. |

Edit | Wow. A lot can happen when you ignore a topic for a day...
My OS was fixed, don't worry. It was on my 83+ years ago, I think when I had only recently installed TI-Connect. ah, memories... |

Edit | Umm, your main problem was when you ran the first program, it was in a folder called eqman. The author of that file forgot to have the program reset the folder back to main. I have had troubles like this before. It could still be a corrupt file, though I think the folder was the main culprit...
And while on the subject of the 89, if you want some awesome games, check out the programming group, Time to Team. Their games are mind boggling... :) |

Total Posts: 35 | another thing... i'm trying to make a program that deals with vectors in space. the thing is, i need to have the calc in parametric form AND in a 3-dimensional coordinate system. i go to 'mode' and i can choose between parametric and 3-d, but i need both. in other words, i need x, y, and z all in terms of the parameter T. can anyone tell me how to set the mode or whatever that will allow me to do this? |

Total Posts: 35 | ok, forget that last thing, i think i can work around it. however, i now have a noobish issue with the programming... i want to prompt the user to enter 3 values (functions of T) for 3 different variables. I then want to perform computations with these variables, including computing derivatives (and 2nd derivs), and then making a vector (1-dimensional matrix).
well i wrote some code, and thought it would work, but i am getting an error saying "must be variable name" at the spot where i am trying to compute, for example x' (x prime, or the derivative of x). this is the code i wrote:
Prompt x,y,z
x'/(x'^2+y'^2+z'^2)^(ª1)/2»tangx
y'/(x'^2+y'^2+z'^2)^(ª1)/2»tangy
z'/(x'^2+y'^2+z'^2)^(ª1)/2»tangz
[tangx,tangy,tangz]»unittang
i don't mean to be a pain, just trying to learn to use the 89Ti, so plz get back to me when u can. |

Total Posts: 35 | alright, forget that, yet again. i realized you gotta use the d() command to find derivatives, and not the shorthand " ' " symbol. i'm used the 86, so now i gotta familiarize myself with this 89Ti. all is good for now, but i'm sure i'll be back when i hit another wall... :img02: |

Total Posts: 1676 | Well, even though you've figured it out...
the ' or "prime" symbol does not necessarily refer to a derivative. It can refer to an alternate x (if you were saying x'), or something to do with x. For example, if I had two similar triangles, with sides a b and c on one triangle, I could refer to the "similar" sides as a' b' and c'.
So as you've already figured out, the calculator cannot know what that means.

EDIT: this is actually shaping up to be a pretty good program. it deals with vectors in space, and so far it can find:
tangent and normal vectors
components of acceleration
arc length and curvature
i will try and keep adding features, and i may even see if i can upload it here sometime down the road.

Total Posts: 35 | okay, well the prog is done, as of now, but since i am not even halfway done with my calc.3 course, i'm sure there' gonna be some formulas etc. that i'll be adding.
as of now, the features of the prog include:
-- various products and uses of products with vectors
...... dot product
...... cross product
...... triple scalar product
...... angle between two vectors
...... projection of one vector onto another
-- conversions between coordinate systems
...... between rectangluar and polar in the plane
...... between rectangular, cylindrical, and spherical in space
-- derivatives
...... finding velocity vector
...... finding acceleration vector
-- tangent vectors and normal vectors
...... unit tangent vector
...... unit normal vector
...... tangential component of acceleration
...... normal component of acceleration
-- arcs
...... length of an arc
...... curvature of an arc
EDIT: if any1 is interested in this program, just lemme know how to go about uploading this thing. :lookaround_a:

...i went to the 'submit files' page, and filled it out and everything, and it said 'successful'. then i tried searching the site for my prog, but it isn't there. will i get some kinda e-mail notification when it's ready, or do i just gotta wait a few days, or what?
