    Ti-89 Unknowns
AI Thread Summary
The discussion revolves around using the Voyage 200 calculator, similar to the TI-89, to solve systems of three equations with three unknowns and to handle 3x3 matrices that include complex numbers represented by i, j, and k. It is confirmed that the calculator can solve these equations and matrices. A specific interest is expressed in calculating the determinant of a matrix, which relates to finding the cross product of vectors in the lower rows. The conversation highlights the need for clear explanations due to the user's limited familiarity with the calculator, and appreciation is shown for the helpful information provided in the forum.

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.
 

Thread 'The Human Cost of AI'

This week, I saw a documentary done by the French called Les sacrifiés de l'IA, which was presented by a Canadian show Enquête. If you understand French I recommend it. Very eye-opening. I found a similar documentary in English called The Human Cost of AI: Data workers in the Global South. There is also an interview with Milagros Miceli (appearing in both documentaries) on Youtube: I also found a powerpoint presentation by the economist Uma Rani (appearing in the French documentary), AI...

Thread 'Urgent: Physically repair - or bypass - power button on Asus laptop'

Asus Vivobook S14 flip. The power button is wrecked. Unable to turn it on AT ALL. We can get into how and why it got wrecked later, but suffice to say a kitchen knife was involved: These buttons do want to NOT come off, not like other lappies, where they can snap in and out. And they sure don't go back on. So, in the absence of a longer-term solution that might involve a replacement, is there any way I can activate the power button, like with a paperclip or wire or something? It looks...
