Use the LOG key for common logarithms, the LN key for natural logarithms. Use the SHIFT of those keys for antilogarithms.

Example: to calculate the natural log of 2, press LN 2 =

Change base log


The TI 86 has two logarithmic functions: natural logarithm (ln) and common (decimal) logarithms (log). If you need the logarithm in any other base than e or 10 you need to use one of the two equivalent expressions
log_b(x) =ln(x)/ln(b) =log(x)/log(b)
Here b is the value of the base of the logarithm and x is the argument (the value whose logarithm you are seeking). Of course the argument x must be a positive number.
Note: On the TI 86 the log function can calculate the logarithm of a complex number, according to the manual.

TI-84 Calculator Gives Me the Wrong Logarithm Solution


"log(2)8" means "common logarithm of 2 multiplied by 8".

The TI-84 has three different logarithm functions.
log is the common (base-10) logarithm.
ln is the natural (base-e) logarithm.
logBASE lets you take the logarithm to any positive base.

If you want the log base 2 of 8, you want logBASE(2,8). You'll find the logBASE function in the catalog, accessible by pressing 2ND [CATALOG] ). CATALOG is the shifted function of the 0 key, the ) gets you to the Ls in the catalog.

On the TI-30X scientific calculator, does the "LN" button perform the same function as the "EXP" button?


If you shift it with the [2nd] button, yes. The [LN] button by itself computes the natural logarithm. When prefixed by the [2nd] button, it computes the natural antilogarithm (the exponential function).

I bought it at a rummage sale and what a manual for it where can i get one? And is different from the TI 30X 11?


You can download the TI-30Xa guidebook from the manufacturer's web site at
http://education.ti.com/calculators/downloads/US/Guidebooks/Detail?id=6132

The TI-30Xa replaced the TI-30X within a year. The only enhancement was the added Constant key.

The TI-30XII, introduced about five years later, is a significantly different calculator, incorporating, among other things, a two-line display.

How do I work the anti log on TI-30X 2s? Where are the buttons?


What you call the antilog is also known as as the power function. More specifically, the inverse of a decimal log is the function 10 to a power, (10^x) It shares the same physical key as the log function. If the calculator has a key marked [LOG] you have to press the [2nd or SHIFT] key followed by the [LOG] key to activate the anti-log.

For natural log (logarithms in base e) the antilog is the exponential function (e^x). It shares the same physical key as the [LN] function.

Where can I find the log values in TI 89


For natural logarithms, you can use the ln function (2ND shift of the X key). For example, the natural logarithm of 3 is 2ND [LN] 3 ) ENTER.

For logarithms to other bases, use the log function (diamond shift of the 7 key). For example, the base-2 logarithm of 16 is diamond 7 1 6 , 2 ) ENTER. If the base is 10 (common logarithms), you can omit the comma and the second argument.

HOW DO I TYPE IN LOG BASE 3 OF 18 IN MY TI 30X


You can calculate the log to any base by using the relationship logb(x) = log(x)/log(b) = ln(x)/ln(b). In words, the base-b logarithm of x is the logarithm of x divided by the logarithm of b.

So, to calculate the log base 3 of 18, press
1 8 LOG / 3 LOG =
or
1 8 LN / 3 LN =

Using the correct key combination to determine inverse log


Hi,
Sorry to contradict you but there are many types of logarithms, the most important ones are
  1. the common logarithms (log in base 10),
  2. the natural logarithms (logarithms in base e)
  3. the binary logarithms (logarithms in base 2)
On calculators, the common logarithms are labeled [LOG], and the natural logarithms are labeled [LN].

The inverse function of the natural log function is the exponential (e^(x)), and the inverse of the log in base ten function is the function ten to the power of. It is called (sometimes) the antilog

Ex:
Question What is the antilog of 3.5678?
Answer The antilog of 3.5678 is 10^(3.5678) = 3696.579068
Verification: log(3696.57908) =3.5678

Hope it helps.
