for example:
sin28°, the calculator would need to be in degree mode right?
sin1, the calculator would need to be in radian mode right?

Yes, that's right. The units should be consistent.

If you want to enter values in radians (or get the results in radians) you should be in radians mode. 1 could be in degrees or radians - only you know what you mean.
It's always nice to do a sanity check, before you start ask it for sin(30) , if it's 0.5 you're in degrees if its some weird number , you're not.
so ask it for atan(1) then divide the result by pi if its 0.25 you are in radians , otherwise you may be in grad.
Best of luck - Mike

Yes. Degrees are a value between 0 and 360; radians are a value between 0 and 2*pi.
You can convert degrees to radians by:
radians * 360 / 2*pi = degrees , degrees * 2 pi / 360 = radians.

Depends on the calculator. At the top of my TI-30 there is a button "DRG" and you can use that to change to mode.

Same thing as matahari. it depends on the make of your calculator. Most of them have a button to press to change the mode. If that doesn;t do anything for you, try to find your mannuel.
