That because you're in GRA mode (so you're entering angles in gradians, not degrees). To go back to DEG mode (where angles are in degrees) press Shift, then press Mode and finally press 4.

How come when i try to do inverse trig function on my fx-9750 gii calculator it says Ma error?

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.

How to use tan^2(55)

It's a quirk of notation. When a book says tan^2(x), it actually means (tan(x))^2. Only the trigonometric and hyperbolic functions seem to get written this way. If one wants the square of a logarithm, for example, one doesn't write log^2(x).

The short answer: if you want tan^2(55), calculate tan(55) then square it.

How do you compute this using scientific calculator log tan 36 degrees 20 minutes?

You may want to insist on using the DMS (degree, minute, second) notation but since 20 minutes is 1/3 of a degree the value of the argument of the tangent function is just 36 and 1/3.
Make sure the angle unit is set to degree.
Set the calculator IO mode to MathIO: Press [SHIFT][MODE ][ : Degree]

Press the[ log] button: log(
Press the [ tan] function key tan (
You see on the screen log ( tan (
Type in 36 [a b/c] 1 [a b/c] 3
Close the two parentheses ))
Press [EXE]
You should get -0.13344355615

To enter an exponent of ten (EE), use the x^10^x key on the bottom row of the keyboard, between the decimal point and Ans keys. To raise a value to another value, use the x^ key to the right and below the circular cursor pad, between the x^2 and log keys. To raise e to a power, use e^x, the shifted function of the ln key on the rightmost column of the keyboard, between the logab and tan keys. To change sign (+/-), use the (-) key on the leftmost column of the keyboard, above the RCL key.

Which keys do i use to put in a logarithmic equation on a Casio fx-300MS?

For logarithms one uses one of two keys
  1. [LOG] for logarithms in base 10. It is in the same column as the F1 key, on 4th row
  2. [LN] for natural logarithms. It is in the same column as the F2 key, fourth row, to the right of the [LOG] key.
No, that is not right. This is for the FX-7400G (as specified in heading). Well too bad. The information is still valid, except for the location on the keypad. That should not be too difficult to find on the FX-300MS keypad.
