The calculator cannot perform any calculation on complex numbers. Sorry.

This video should explain how to do an internal rate of return.

Good luck,

Put the calculator in STATistics mode (maybe called SD). Enter the data then use a key called sigma_d.

That would be the funny check mark thing.

This
calculator does not support the modulus operation directly, you have to
simulate by a divide followed by a subtraction and a multiplication.
Suppose you want to calculate 256 mod 17:

- Key in 256 [÷] 17 [=] and get the result 15,0588...
- Note the 15 in front of the decimal separator and key in [−] 15 [=]
- Get the modulus: [×] 17 [=], result should be 1.

Press SHIFT [pi]. pi is the middle key on the bottom row of the keyboard.

Use a soft piece of cloth. Do not press too hard.

That is the correct value for the cosine of 60 radians.

If you want the calculator to use some other measure for angles, press the MODE key repeatedly until you get to the "Deg Rad Gra" screen, then press the digit corresponding to your choice (degrees, radians, or grads). See "Configuring the Calculator Setup" in the second column of the first page of the manual: http://www.fixya.com/support/p1400062-casio_fx82ms_scientific_calculator/usermanual-BA0F781-pdf

17/6=12/6+5/6

17 mod 6=5

17 mod 6=5

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. Some sophisticated calculators have generalized equation solvers that can handle equations much more complicated than the quadratic, but the fx-82 isn't one of them.
