Hi I know this may sound dumb, but I was wondering if someone could please outline which topics require radians mode and which require degrees mode on a calculator. This has caught me out a few times when I haven't switched to the right one and I want to make sure that it doesn't cost me silly mistakes! Thanks in advance! :)

Good q, i'd like to know if there's a way to not forget to change.
have 2 calculators one in radians and one in degrees label each one with R and D, whenever you see a trig question with any trig ratios... or the value pi radians should jump to your head. read the question carefully before thinking its radians
ie
tan(pi^degrees)
