Bought a Casio FX-260 calculator. Im trying to find out how to input a trig formula. E.g 2/cos(70)= 5.84 When I do put this in the calculator in scientific mode it gives me a different answer. Help?

I'm guessing that your calculator is set to radians or gradians (or degrees, if you are looking for a result in radians or gradians).

Try changing this and hopefully it will work.

Otherwise, post again!

Good luck,

You probably mean Radian mode. (the Radium is a radioactive chemical element, with symbol Ra on the Periodic table of the elements).
To set angle unit to radians, Go to the RUN screen.Press SHIFT MODE to enter SetUp. Scroll down to line ANGLE; Highlight the line and press F2 to activate the TAB RAD on the screen. Angle unit will be set to radians, until you decide to change it again.

I'm trying to graph in radians on a casio fx-9750ga plus, but it doesn't show up on my screen. what should i do?

To get results in radians you must configure the angle unit to be degree.
  1. In Run screen press [SHIFT][MENU] to access (SETUP).
  2. Use Down arrow to highlight the line Angle :
  3. Press F2 key to select the TAB Radian.
  4. Once you do that all values (input of trigonometric functions and polar graph functions OR output of inverse trigonometric functions) are in radians.
If your function is periodic (and all trigonometric functions are) set the window dimensions Xmin
= negative (2 or 3)P and Xmax) = (2 or 3) PI. Adjust if necessary to a smaller domain.

Casio fx-300es---how to convert radians to degrees

You use the key combination [SHIFT][ANS] (DRG>).

If the default angle unit is degree
Type in the angle value in radian, say 1.2.
Press [SHIFT][ANS] (DRG>).
The screen displays 1: deg symbol, 2: a raised r for radian, and 3; a raised g (for grad).

1.2 [SHIFT][ANS] (DRG>) [2: raised r] .
The screen displays 1.2 with a raised r to the right of the 2.
Press [=].

The answer is 68.75493542
