Use the "x^-1" ("x-superscript-negative-one") key just below and right of the big round cursor pad.

For example, to invert 2, press 2 x^-1 =

Use the key next to which is the marking nPr, for permutations, and the key nCr for combinations. In all probability, the functions are accessed by pressing the SHIFT key first. To use these functions, enter the larger number (n), press the key or key sequence then enter the smaller number (r). I cannot say about the binomial function (I do not have the hardware with me), and do not really want to second guess you: you do not specify the type of problems you have in mind.

You can not do it unless you know the measure of the central angle sustending (supporting) the arc. If the angle is known, you use the proportionality relation that follows:If angle is in degrees(length of arc) / circumference=(measure of central angle sustending arc)/360.Here the circumference is 2*PI*radius.If angle is in radians , the relation is somewhat simpler,arc length= (radius length)* (angle measure in radians)It is clear that in the last relation, the unit for the arc length is the same as the unit for the radius.

As per Wikipedia, "As the function f(x) = bx is the inverse function of logb(x), it has been called the antilogarithm." For example using base 10, log of 1000 is equal to 3, and the antilog of 3 is 1000.

In your calculator try to use SHIFT LOG (10^x). Please remember this is for base 10.

Maybe it was set to "FIX X" where X is the number of decimal places. Try to press the mode key until you see below:


Select Norm by pressing 3.

To clear independent memory (M), please try the following in order:

1. press "0"
2. press "SHIFT"
3. press "STO"
4. press "M+"

Press Mode a number of times until you see below:



Then press 3 to select Norm.

Press Mode a number of times until you see below:


Then press 3 to select Norm.

There is no Inverse Cotangent on the Calculator, but you have Inverse Tangent.

Cotangent is just the reciprocal of tangent.




Just inverse the fraction and use inverse tangent to get its cotangent. Hope this helps.

You need to use the "SHIFT" button to get the inverse of sin/cos/tan. Also, set the Mode to 1 if you want it in degrees.

To get out of the fixed decimal mode, press the MODE key until you see the screen giving you the three options "Fix", "Sci", and "Norm". Select Norm 1 or Norm 2. If you select a Sci mode, you'll get "SCI" on the screen in place of the "FIX".

You don't. The calculator can display only ten digits in a number. This number has eleven digits to the left of the decimal point, so the only way the calculator can display the most significant digits is to switch to scientific notation.

The good people here at Fixya.com actually have a manual for that calculator on hand. This should answer any questions you have about the calculator and should walk you through numerous different problems so that you understand how to use it better.

Best of luck to you mate!

ln(x+1)-ln x=ln 4

Press the [MODE] button a certain number of times until display shows a rectangle inside which Deg Rad Gradappear on the top line and 1 2 3 on bottom line, with 1 under Deg, 2 under Rad, and 3 under Grad.
Press 1.

This is all about adding fractions. Think about what needs to be true about the two fractions to be able to add them (and make all fractions improper before adding) Searching for this on wolfram alpha will give you more of the information you need. You aren't going to get the answer from this site, we're just here to help you learn how to do these things.

Display Format

To change the exponential display format, press the [MODE] key 3 times.

Fixed number of decimal places:

Press 1: Scientific Notation: 0

Press 2: SCI: 0

Press 3: NORM

You will then be prompted for NORM 1 or NORM 2. CHOOSE NORM 1

To return the calculation mode and setup to the initial defaults, press [SHIFT] [CLR] [2]

[=]. This will return the calculator to the following settings:

Calculation mode COMP

Angle unit Deg

Exponential display format Norm 1

Fraction display format a b/c

Decimal point character Dot

Percentage Calculations

You have your calculator set to give your answer in scientific notation. If you would like it to give your answer in decimal form you need to change the settings. On my calculator which is an older version, you just press [mode] three times. On your screen you will see fix sci and norm as well as the numerals 1, 2 and 3. press [3] on your key pad. You should see norm 1~2? then press [2] on your keypad and this will have changed your settings back to plain decimals.
I hope this helps!

I do not think you will find the zoom button on the Casio FX300ms. That button or function exists only on Graphing calculators (those that have a large display screen and have the capabilities to draw graphs of functions). As far I as know this calculator cannot draw graphs.
