Inverse log ti-36x pro - Texas Instruments TI-36X Pro Scientific Calculat

You do dimensional analysis by hand.

Its been a while since I used it but I normally enclosed the number in braces and then raised it to the power of (-1)...Make sure you use the braces

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.

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]

The antilog functions are the 2nd functions of the log functions on the top row of the keyboard.

To calculate the natural antilog of 3.1, press 3 . 1 2nd LN
To calculate the common antilog of 3.1, press 3 . 1 2nd LOG

For the inverse natural log, press 2nd LN. For the inverse common log, press 2nd LOG.

For example, to calculate the inverse natural log of 2, press 2nd LN 2 ENTER and you'll get about 7.389 .

The inverse key is marked "1/x" (second key on the third row). The natural logarithm key is marked "LN" (fourth key on the top row).

Hi,
I would certainly upgrade my choice to the FX-991ES. It can do (numerical) integrals, derivatives, it has 40 physical constants (instead of 8). It can do unit conversions, and the Natural display is a real pleasure.
Don't get me wrong, I am no TI calculator basher. I have just bought the TiNspire, AND TINspire CAS. I have a TI92, a TI83, Ti BA 35Solar.
If you do become an engineer, the calculators you might want to use (not during the exams) are the TI 89 Titanium, HP49G+/HP50G, the Casio ClassPad 330. You see I recommend the TI89 Titanium because there is a wealth of Engineering programs written for it.

Hope it makes your decision easier.

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?
