How do I put Casio FX9650GII in degree mode - Casio FX9750GII Graphic Calculator

fx-82MU?

If you mean fx-82AU, press SHIFT [SETUP] then 3, 4, or 5 to select the desired angular mode.

If you mean fx-82MS, press MODE then 1, 2, or 3 to select the desired angular mode.

Casio calculators almost always have the angular mode in either the MODE or SETUP menus.

Press SHIFT [MENU] to bring up the setup screen. Move down to the "Angle" line and set the desired mode.

Press SHIFT MODE 3 to switch to degrees.

Press [SHIFT] [MODE] [3] to switch to degrees.

Open the [Run] application screen.
Press [SHIFT][MODE] to enter (SetUp)
Use down arrow key repeatedly un til you see the line Angle:
Press the F1 key to select Degree as angle unit.

Press SHIFT MODE to access (SETUP)
Press 3:deg for degree OR
press 4:Rad for radian.

There is nothing special about the equation. tan(52) is just another number.
Isolate the unknown to get
X=18*tan(52)
I assume that the angle value is in degrees. To set it, press MODE 0 to use the usual computational mode, then set angle unit to degrees by pressing MODE 4.
Once this is done, type in
52 TAN * 18 =

Hi,
To change the default angle unit, you press the [MODE] button a certain number of times until display shows a rectangle inside which Deg Rad Grad appear on the top line and 1 2 3 on bottom line, with 1 under Deg, 2 under Rad, and 3 under Grad.
Press the number key corresponding to your case, 1. All angle values you feed the trigonometric functions will be considered to be in degrees. If you use the inverse trigonometric functions to find angles, the results will be in degrees.

Hope it helps.

set it up in correct rig mode, mode button (several times) until you get a window showing deg - rad - grad, choose deg (degree mode)
