The log base 10 function has an inverse: It is the 10 ^x function. It shares the same physical key with the decimal log. Use [SHIFT][LOG].

The natural log (LN) has an inverse alos and that it the exponentila function e^x. It shares the same physical key with it.

Just wondering if the other functions are working.

The manual references setting up angle unit and setting up the "comp for mode" in the setup.

The keys you should be pressing to do this calculation are on page 51 (2-31) of the attached manual.

Check the calculator with a simple 2X2 matrix that you can invert by hand easily and see if it gives you the wrong inverse for it. It is also possible that YOU made the mistake.

The inverse of log functions are power functions.

Inv of ln is exponential (e^x)

Inv of log in base 10 is 10^(x)

A function and its inverse usually share the same physical key. One function is accessed directly, the other by using the SHIFT or 2ndF key.

For the reciprocal of a number, enter the number then press the key marked with an x^-1. You might have to use the SHIFT key first. For inverse of trigonometric functions use the SHIFT key followed by the function name. The inverse of LN is e^x. The inverse of log is 10^x. To calculate the inverse of a matrix, enter the name of the (already created) square matrix then press x^-1.

By 'log inverse', you presumably mean the inverse of the logarithm function. There are two logarithm functions on most scientific calculators. Firstly [ln], or natural logarithms, to the base e, where the inverse is e^x. Secondly [log], or logarithms to the base 10, where the inverse is 10^x.

Example 1 : ln(2) = 0.69314718 so e^0.69314718 = 2

Example 2: log(2) = 0.301029995 so 10^0.30102995 = 2

Example 1 : ln(2) = 0.69314718 so e^0.69314718 = 2

Example 2: log(2) = 0.301029995 so 10^0.30102995 = 2

Depending on the actual log function you are talking about, the inverse function (what you call the anti log) can be one of several things.

The inverse of the natural log (LN) is the exponential function** e^x**.

**If y= ln(x) then x=e^y **

On a calculator functions that are inverse of one another share the same physical key.**If one function is marked on a key, the inverse function is usually the SHIFTED (or 2nd) key **

The inverse of the common (decimal logarithm) is the power function with 10 as base.

Example:** if y= log(x) then x=10^y**

For an arbitrary base (must be positive)** if y= log_b(x) then x=b^y**.

Note: I do not think that the FX-300ms can perform log calculations in bases other than e (natural log) or 10 (common decimal log).

Actually, it's the inverse of log, or 10^x, to do so, simpily press [2nd] [LOG].

My way is really slow b/c I don't know the right way, but I always clear my memory (SHIFT, CLR on the 9 button), then type it in as an equation, for example: log(X)=-15.3, then press SHIFT, and SOLVE (on the calc button), then press =. It freezes up the calculator for several seconds though =/
