Voyage 200 help

[Bradracer18]

Hey guys, I was wondering.....Can I make my voyage 200(basically a Ti-89)....solve for 3 equations and 3 unknowns? If so, how?

Also, I was wondering, can I make it solve 3x3 matricies, which include numbers on the lower 2 rows....but the top row(across)....has i,j,k on it. Anyway to use the calc to solve this?

Thanks for the help.....I know little about this calculator, so explain clearly.

Thank you,
Brad

I suspect that you don't want to "solve the matrix" but in fact want to find the determinant of the matrix (i.e. calculate the cross product of the vectors in rows two and three).

yes, that is what I'm looking to do cristo. Just looking to speed things up a bit, and possibly stop some errors.



And.......thanks ranger, I think that pretty much answers my equation question.
