I am learning about inverse functions in Algebra 2. I have a Casio fx 300MS calculator and cannot locate the key. I do hope you can help.

Thanks,

Joe

Hello,

Use [SHIFT] [COS^-1], [SHIFT][SIN^-1] and [SHIFT][TAN^-1] the keys are the same as the direct function, but they are accessed via [SHIFT].

Be carefule with the angle units when handling trigonometric and inverse trigonometric functions

Hope it helps

Mode>choose "5"

choose equation format "4"

input the coefficient for a which is "1" and hit "="

input the coefficient for b which is "4" and hit "="

input the coefficient for c which is "3" and hit "="

input the coefficient for d which is "12" and hit "="

Hit "=" for X1

Hit "=" again for X2

Hit "=" again for X3

SOURCE: I need to find the antilog to -6.80 on a casioi fx-300ms calculat

Alot of people have this doubt, so I might as well make it clear.

Press the 10^x button (while pressing SHIFT, of course; it's exactly above the LOG button) followed by the number whose antilog you desire.

Example :

Let's say we need antilog(-6.8),

1. Press SHIFT, followed by LOG (i.e 10^x); this'll display a 10 on the screen;

2. Type in -6.8;

3. Press "=";

4. This'll display 1.584893192x10^-7 as the solution, which is correct!

5. Bye, lol :P

By [2nd] log and then the number it's the antilog.

Rate me please, thanks.

SOURCE: how to calculate inverse of a 3x3 matrix in casio

Hello,

Here is the solution for th FX-991ES.

Hello,

The error may be due to the key you used to signifie
inverse. It says in the manual that you should use the key x^-1 not the
one used to input general powers.

Here is screen capture from the
Appendix to the manual. The picture shows the sequence of keys to press
to obtain the inverse of a 2x2 matrix. It is taken from page 41 of
Appendix

The matrix used in the exemple is

a_11=2 a_12=1 a_21=1 a_22=2

Here is the link to download the manual and the appendix

The link is for FX991ES. Look there foe you manual.

Hope it helps

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.

Good luck. If unsuccessful, please repost.

To calculate the natural antilogarithm (inverse logarithm ) of a number, press SHIFT [e^x] then enter the number and press =

The e^x function is the shifted function of the ln key.

For example, to calculate the inverse logarithm of 3, press SHIFT ln 3 =

The e^x function is the shifted function of the ln key.

For example, to calculate the inverse logarithm of 3, press SHIFT ln 3 =

On the fx-260, press 5 / 9 = SHIFT SIN .

On the fx-300MS, press SHIFT SIN ( 5 / 9 ) = .

The key is marked "x-superscript-negative-one" and located just below the "SHIFT" key.

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 inverse function of the natural log (ln) is the exponential function (e^x). They share the same physical key. One is direct access key and the other is the shifted one: You have to press [SHIFT] to enable it.

The inverse of the log function is the function 10^

antilogarithm of (x)=10^(x)

The function shares the same physical key as the [LOG] function. To access it you press [SHIFT][LOG].

The hyp key is used with the cos, sin, and tan keys to compute the hyperbolic cosine, hyperbolic sine, and hyperbolic tangent functions (and their inverses).

The hyperbolic functions are computed the same way as the trignometric functions: simply press the hyp key just before pressing the desired trig key.

because cotangent, cosecant, and secant are all inverse trig functions, just type in 1 / |shift| trig function and the number if you are finding the angles. It might not be a dedicated button, but its an extra push, and it will give you the same result. *note that I put the shift press only because that is how you get the inverse tan to get an angle from a tan ratio.*
