##### 3-D Vector Plotter
« on: March 06, 2007, 10:25:00 am »
This is a program I started making a while ago, although I never really got around to finishing it.  I might later on, but I'm going to put it online for anybody to download it in case they want to finish it.  It is in TI-BASIC for the TI-83+/TI-84+ series.  It definitely isn't completely optimized at the moment, partially because I wanted readability.  It is meant to serve as an aid to those learning about vectors because it offers (or it was intended to offer) a few handy features:

- Visual plotting (including addition and other operators) of 3-D vectors
- Conversion between equation formats
- A table of values for vectors
- The ability to calculate the angle between two vectors
- The ability to calculate where two vectors intersect

So far, all it can do is visually plot 3-D vectors, which is kind of cool, and adjust the window.  Here's a screenshot of it:

that's pretty cool.  Can the camera by shifted over or is the original always kind of fixed there on the left?

It can be shifted over.

Nice work with the graphing ability.  :thumbup:

Perhaps you add some of these features (should be easy, as I have already done this on my 89):

- vector length
- unit vector (and graph)
- dot product
- cross product
- triple product
- projection
- bound vectors
- check for orthogonal
- check for orthonormal

Well, I could, but I've kind of stopped working on this.  I might continue working on this sometime, though.  Good suggestions, though.

Yeah dot product would be a great addition
There are 10 types of people in this world-- those that can read binary, and those that can't.
