# 20 Most Recent Casio FX-82MS Scientific Calculator Questions & Answers

I think the problem with this equation comes when x = 0. At this point, it is undefined. Thus, it is a horizontal line y=-2, except when x=0. This is normally signified by putting an open circle when x=0.

I hope I answered you question. If not, repost.

Good luck,

Paul

Use the cosine, sine, and tangent buttons on your calculator and invert them with x ^ -1 key.

For example, csc = 1/sin. So for csc 30 degrees, so sin 30 degrees, then hit the x^-1 key.

Good luck.

There are several ways to find the cube root of a number on a calculator. On this calculator, we can use the nth root button, by using the yellow shift button with the ^ key. Another way to do this is just to use the ^ key.

For example, the cube root of 8 is performed by the following key sequence: 8, shift, ^, 3.

Another sequence is: 8 ^ (1/3)

Good luck.

There is no easy solution for a cubic equation such as this, unlike a quadratic equation which has a simple solution that we all learnt at secondary school.
Google for cubic or this gives a good explaination

There should be a small reset hole! Press this in with a paper clip or similar for about 10seconds

There are two separate issues here.

The "D" at the top of the screen indicates that the angular mode is set to degrees. You can change the mode by pressing the MODE key repeatedly until you get to the "Deg Rad Gra" screen and then choosing one of them, but no matter which one you choose you'll get a letter at the top of the screen reminding you of the current mode.

To change the way numbers are displayed, press the MODE key repeatedly until you get to the "Fix Sci Norm" screen and then choosing one of them. You can choose Fix and then press a digit specifying the number of digits after the decimal point, or choose one of the Norm modes and let the calculator show all nonzero digits after the decimal point.

The fx-82MS does not have any built-in functions for calculating the normal probability distribution or its related values. You can calculate it using the defining function or any of a large number of approximations. Alternatively you can look up the values in a table.

Some advanced calculators have the functions built in, and programmable calculators can be programmed to give them. Sadly the fx-82MS is neither.

For more about the normal distribution, see http://en.wikipedia.org/wiki/Normal_distribution

You can do it the same way people did it before calculators were invented. Just use the quadratic formula: http://en.wikipedia.org/wiki/Quadratic_formula.

Here is a sample of the percentage calculations that the calculator can perform. You will not see among them the conversion from decimals to percentages.
To convert from decimals to percents move the decimal mark 2 places to the right and append the % sign.
To convert from percents to decimals, move the decimal mark 2 places to the left.

Most likely you set the angle unit to degree. As long as you do not calculate trigonometric ratios you won't get incorrect results. Switch the angle mode to radian if that is what your calculations require.

Use the DMS key marked degree, apostrophe, double quotation mark.
Lets us call it [DMS]
To enter an angle in degree minutes seconds or hour, minutes, seconds, type in the number of degrees, press the [DMS] key, enter the number of seconds, press the [DMS] key, enter the number of seconds then the [DMS] key. Press = the calculator displays the value in DMS units. If you press the DMS key again the number displayed is converted to decimal degrees.
Example:enter 12 degrees, 15 minutes, and 25 seconds
12 [DMS]15[DMS]25[DMS] =
Calculator displays 12 deg 15'25"
Press the DMS key again and you see 12.2569444

Press and release the SHIFT key at the upper-left corner of the keyboard, then press and release the EXP key at the center of the bottom row.

Note that the EXP key has the Greek letter pi printed above it in yellow.
