So tell us all, jaxie, how much 3 degrees time 5 degrees?
the question lacks enough information to make sense.


There's plenty of information. You said:

"Think about it. the error of the mag compass reading TIMES the error of the
helmsman gives the potential error UP TO THAT POINT. Already, you are
waaaaaaaaaay beyond 2*. waaaaaaaaaaaaaaay beyond."

How do you multiply the two errors? Is the total possible error more or less
than the sum?
