Question about Office Equipment & Supplies

I get f(x) = -x as the inverse of f(x) = -x.

I set up some tables to see if this is correct.

x ' y

-------

-2 2

-1 1

0 0

1 -1

2 -2

For the inverse function, we should be able to put in y and get back x x ' y

-------

2 -2

1 -1

0 0

-1 1

-2 2

The equation of this function is f(x) = -x.

Good luck.

The inverse cosine function is defined for arguments from -1 to +1. 6 is outside of this domain, thus the error. Do you get an error if you try the inverse cosine of 0.6, for example?

If you're getting the same error for the inverse tangent, could you post an example?

I suspect that you are confusing things a bit.

The inverse sine, called the arcsine is a function defined in the closed interval [-1,1]. And so is the inverse cosine. Any value outside this interval will give you a non-real result (meaning a complex one).

There are no limitations on the domain of definition of the inverse hyperbolic sine or sinh^-1

If your input value is**allowed to be complex**, the arcsine function gives a complex value. See the screen capture

The inverse of a function usually shares the same physical key as the direct function.

The sine and cosine function have a range between [-1, 1]. The domain of their inverse functions is [-1,1]. So 20/1 which is 20 is out of the domain of definition of the functions. No limitations for tangent and cotangent.

That depends on what you want to invert.

If you want the multiplicative inverse (1/x) then it's the "1-superscript-minus-one" key just below the "MATH" key.

If you want the additive inverse then it's the "(-)" key just to the right of the decimal point key.

If you want the inverse of many of the built-in functions (like the trig functions) then press the "2ND" key at the upper-left before pressing the function key.

For the inverse of some functions you'll have to go through the menus.

If you have a particular inverse in mind, please reply to this post and specify exactly what you'd like to invert.

It is much more enlightning to tell us what you want to do rather than talk about something that does not exist. And one thing that does not mean anything is that ellusive INVERSE key that everyone and his dog is looking for.

The additive inverse of a number a is its opposite (-a). The key to use is the change key (-).

The multiplicative inverse of non-zero number a is its reciprocal 1/a

The inverse of the natural log (LN) function is the EXPONENTIAL function e^(x). On most calculators if one function is accessed diectly (the marking is on the key), its inverse is accessed by pressing [SHIF] (Casio, or [2nd] (TI) or [2ndF] (Sharp).

The inverse of the function raise 10 to a power [10^x] is [LOG]

Similarly, the inverse of the sine function SIN is the arcsine [sin^-1]. To access the latter, it you press [2nd][SIN]. The same is true for arcosine [2nd][COS], and arctangent [2nd][TAN]

The inverse of the square functions [x^2] is the square root function [2nd][x^2]

Inverse of x^3 is cubic root

This is just a quick overview.

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]

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).

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.
