Finding least squares solution of Ax=b?

Click For Summary
To find the least squares solution of Ax=b on a TI-89 graphing calculator, users should input their x values into one list and their y values into another. The process involves accessing the statistics menu, selecting the linear regression option, and executing the calculation to obtain the least squares solution. While specific commands for the TI-89 were not detailed, the approach is similar to that of the TI-84, which involves navigating to the 'stat' menu, choosing 'calc', and selecting the linear regression function. This method is useful for verifying answers to linear algebra problems.

I have a ti-84 and i am not with it right now so don't quote me on this lol but did you enter your x values into L1 and your y values into L2? on my Ti84 after that, you go to stat --> calc --> 8 (which is LinReg(a+bx)) and press enter.

Thread 'ChatGPT Examples, Good and Bad'

I've been experimenting with ChatGPT. Some results are good, some very very bad. I think examples can help expose the properties of this AI. Maybe you can post some of your favorite examples and tell us what they reveal about the properties of this AI. (I had problems with copy/paste of text and formatting, so I'm posting my examples as screen shots. That is a promising start. :smile: But then I provided values V=1, R1=1, R2=2, R3=3 and asked for the value of I. At first, it said...
