Need help with function of my calculator

[thecoolnessrune]

I have a TI-89 Titanium. It can do nearly everything, its really cool. However, my calculator seems set up wrong because when i enter a statement such as (ln(12))/(ln5)), it just repeats that statement. I want it to solve to a general number. The TI-83 emulators here do, so how can I make it do it on my TI-89?

See below for updated question

Don't you hit Fn + = for that? It's been a long time since I've toyed with a TI calculator, but I know there was an extra ability for the equals button.

You have to approximate the answer. IIRC, that's the "diamond" function of the enter key.

 

[MrDudeMan]

you have to hit diamond (green) and then =. regular = reduces fractions or solves for variables. diamond + = solves/approximates.

Your answer got me thinking. And sure enough, 3rd (green diamond ) function plus the enter key forces it to give an approximation. Thank you sooooo much dude! This helps a ton!!


for you!

Dam I love ATOT! thanks all.. If I may ask another question, is there any where I can go to force it to approximate to a certain number of decimals?

yes, in the mode menu. you can select float(1-12) or something like that, scientific, and a few other things.

I like the times .99999999999999 answer

Alright, new question. How can I get my calculator to do more than square roots? I know you use the 2nd FUNC button followed by the multiplication button to do a square root, but how can I enter my own root?

You all have been so helpful, and I humbly ask that you can provide me yet another answer to this thing ^_^*

...?

What about paging through the large book that came with it?

What do you mean 'my own roots'?

sqrt(2) = 2^(1/2)
3rd root of 5 = 5^(1/3) and so on

I never thought about writing it that way.... Thanks for the quick response.

As for reading the large book, I have. I didn't see it mentioned anywhere so I thought it was so simple they didn't even bother writing it.. I can see I was right Silly me..


Regardless, for you. ^_^

Lol, its tough to see posts that haven't been posted yet!

The manual contains a lot of information, for instance: if you go into the operations tab and select MATH there should be an option xSQRT which allows you to put a number infront of the equation and it will take that root. However the x^(1/y) is much easier.

I thought everyone has superpsychopathicnymphomania..... I'm just special ?

AWESOME!!

But I do concur, I like the original way better.
