Calculators Plotting a Graph from a Table of Values - Help Needed!

AI Thread Summary
To plot a graph using a table of values on a TI-89 calculator, first access the Data/Matrix editor to input your x and y values. You need to assign a variable name for each column, such as 'c', which will represent your data. After entering the values, navigate to the Y= screen and select the plot type you want. For the x and y axes, use the variable names corresponding to your data columns (e.g., c1 for x and c2 for y). Once set up, hit enter to graph the data. This method allows you to visualize your complete table of values effectively.

To enter numbers into the table, select the Data/Matrix editor, and a screen will pop up. It will want you to enter a variable name. In mine, I chose 'c'. This simply is the name of each column in the table. When you hit enter, the table will appear, and numbers can be entered, much like in Microsoft Excel.
If you've already entered the numbers into the Data/Matrix editor, go to Y= screen and scroll above y1. At plot 1, hit enter and select what kind of plot type you want. Then for x and y, enter the variable above each column of the Data editor. (i.e. c1, c2...whatever variable you selected when the Data/Matrix editor was first used). Then hit enter and graph. Hope this helps.
 
Sorry if 'Profile Badge' is not the correct term. I have an MS 365 subscription and I've noticed on my Word documents the small circle with my initials in it is sometimes different in colour document to document (it's the circle at the top right of the doc, that, when you hover over it it tells you you're signed in; if you click on it you get a bit more info). Last night I had four docs with a red circle, one with blue. When I closed the blue and opened it again it was red. Today I have 3...
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...
