I just had a second (maybe even third) year engineering student ask me, during a quiz I was proctoring, what the conversion between degrees and radians is.
For you non-engineers, I don’t know which dumb question that relates to in your life, but for engineering students that’s a ridiculously stupid question for someone at that level.
Not only should the student know that conversion from experience and practice, the student should have have been able to think through the conversion. “How many degrees in a circle? 360. How many radians in a circle? 2 pi. Ergo, 360 degrees equals 2 pi radians. Ta da!”

And here I was trying to solve the problem using the right hand rule……with my left hand.
