Calculators Not getting the right answers for sine, cosine and tangent with TI-89

AI Thread Summary
Issues with obtaining correct answers for sine, cosine, and tangent functions often stem from whether the calculator is set to radians or degrees. To check the setting on a calculator, access the F2 menu and look for the options labeled "radians" and "degrees." Highlight the desired option and press enter to select it. Ensuring the correct mode is crucial for accurate trigonometric calculations.

How do I do that? I just got this calculator.
 
click on F2 (window)

look for radians | degrees

and highlight the one you want and click 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...
