I'm trying to figure out a way to find 13/16 into a percentage on my calculator, it's a Ti-36X.... is there a button or something? Help please

Texas Instruments has the guidebooks for many of their calculators on their support page. http://education.ti.com/en/us/guidebook/search/scientific-calculators is the best starting point.

The direct link to the TI-36x Solar Guidebook is http://education.ti.com/download/en/US/8E1BED432FAC4E4FB5E7A01102F78382/BDD801AB9F3244E3B275AB93FD4F2238/36x-eng.pdf . If you click Continue as Guest, you should be able to download the PDF.

I hope this helps.

Look in the back of the calculator, some TI models have a pin hole to hard reset the calculator.

In the top right corner of the screen. There is a button that says 2nd.

Press 2nd then press the button that is four buttons further down on the same row of buttons.

You may download a copy of the guidebook here.

The inverse of what&? Each inverse function uses the same key (shifted) as its direct function. For the reciprocal key look for x^-1 or [1/X]

Basically you first have to put your answer into scientific notation by pressing the 3rd key then the 6 key. The screen display should change to one big zero and two small zeros.

I was workinggon the same problem with a -log of a chemistry problem to get pH and I knew the answer because I calculated it on it TI-85, but we are not allowed to use graphing calulators on the exam (:-((() so I had to figure out how to do it on this one!

For example, I had pH =-log(2.828947x10^4)

On the TI-36X you change to scientific notation using the instructions above. Once the three zeros enter on the screen:
[4]
[-]
[2nd]
[10^x]

1^-04 should appear on screen, then you multiply by 2.828947

[x]
[2][.][828947]
then your screen will show the answer in scientific notation.

2.828947 in big numbers and in small numbers -04
From there you simply press:
[log]
and your answer will show up as a negative number. Just take the absolute value of that and you have your answer. Took me like 30 minutes the night before a huge chemistry exam to figure that out! Hope it helps someone!

That depends on what you mean by "solve probability." You could study probability for a year in college and not come close to covering all the types of probability problems. Do you want the number of combinations or permutations? The upper or lower tail of some probability distribution? The inverse distribution?
