Question about Texas Instruments TI 30XIIS Scientific Calculator

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 =

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.

"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.

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).

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.

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.

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.

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 =

Hi,

Sorry to contradict you but there are many types of logarithms, the most important ones are

**[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.

You must enter 100+10%100 or 100+10%(100). This will give you the correct answer of 110.
