Question about Texas Instruments TI-84 Plus Calculator

Ad

Sorry, but it takes sometime to be well familiar with the calculator. The E in the result is a short-hand notation for times 10 to a power. What you got is 4x10^(0) which is just 4.

Your calculator is doing that because it is configured to display result in SCIENTIFIC format.

To revert to the format you may be more accustomed to,

- Press the [MODE] key
- The first line of the displayed screen will show NORMAL SCI ENG and the cursor blinking on SCI or ENG.
- Use the left arrow to highlight NORMAL and press ENTER.
- Press [2nd][MODE] to (QUIT) and go to main calculator screen.

Your right you should be in degree mode. However, my guess is you are somehow entering in cot wrong in your calc. Recall cot = 1/tan! In your graphing calculator enter: 35(1/tan(61) = 19.4.

Hope this helped!

That is what I get with your numbers on the TI84 Plus Silver Edition 0.1870313608. I get the same on the TI83 Plus. What can I say?. Apart from an error entering the numbers ( a 6 for a 9, a 3 for an 8) I cannot think of anything else. Sorry.

Ti 83 and ti84 really have no difference and operate the same. There was something different or you had varibles used by multiple programs that conflicted w/ the ti84 and it would have done the same on the ti83. If you like to rework it and need help email me at raklein62@yahoo.com
