## Math equation problem

Asking for a friend:
I have a question about how to work out a student's exam mark.
Unit 1 is worth 60%, Unit 2 is worth 40%. Both units are marked out of 80. For example, a student scores 67/80 on unit 1 and 69/80 on unit 2. What is their overall mark?
Thanks for any help!

## Principle domain of a polar equation?

I need help understanding the "principle domain" (a term only my professor seems to use) of a polar function.

I suspect that if MeFi could identify the more common name for this, uh, procedure, I'd be set.
