How do i do "regular" math, calculator stuck on GRAD/DRG...

Change to a different angular mode. Press the DRG key, use the left/right arrow to select the desired mode, then press ENTER twice.

Be aware that whatever angular mode you select, the display will show either "DEG", "RAD", or "GRAD" to indicate the mode.

You don't.

Angles can be measured using three different units: degrees (360 degrees in a circle), radians (2pi radians in a circle), or grads (400 grads in a circle).

Pressing the DRG key cycles through the three modes. No matter which mode you select, one of the annunciators will appear on the screen to indicate the current mode.

Press the DRG key to cycle through the three angular modes: degree, radian, grad. Be aware that one of the indicators will always be lit to show which mode is currently set.

Both FIX and SCI are lit? What happens if you press SHIFT MODE then select either FIX or SCI?

hi emily, most scientific calculators have a feature to switch between deg-rad-grad. lookout for a switch DRG or so on the keypad, this feature might also be activated via a "second function" operation. check out your user manual for further in depth help.

Your calculator is set for GRAD instead of DEG, it means that it takes your input in gradian instead of degrees. You should press the DRG button until it displays DEG instead of GRAD.

Use the relation cot(30) =1/tan(30).
Press [DRG] to set the correct angle unit (degree, radian, or grad). If you are working with degrees the DEG display indicator should appear on screen

You then type
28 [/] ( 30 [TAN] ) =

Hello,
To convert a displayed number from degree to radian, press [2nd][DRG->] once. Each time you press the two keys in sequence you change from deg to rad to grad to degree and so on.
Hope it helps.

That's the Binary code. You have to change it back to the Decimal code. Try to change it back with the shift and Mode buttons

Try this. Press MODE and then number 1 ... This worked to me. And then with DRG you can change to DEG, RAD or GRAD ... I hope I helped :)
