Calculators Finding unknown terminal value of integral with TI-89

Click For Summary
To find the unknown terminal value k in the integral ∫2^k (3x + 4) dx = 43.5 using a TI-89, users suggest setting up the equation in the calculator's integral function. The integral can be evaluated with the limits from 2 to k, and the result should be set equal to 43.5. Participants discuss the importance of correctly inputting the function and limits to obtain the desired value for k. Some users also mention alternative methods if a TI-89 is not available. Ultimately, the TI-89 can effectively solve for k by using its integral capabilities.

\int_2^k \! (3x+4) \, \mathrm{d} x = 43.5

how would I use the TI-89 to solve for k?

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...
