I am stuck with my trig homework. My teacher isn't the best at teaching this stuff and the power point slides from my school stop before they get to this. Also in the answer book (and text) it doesn't really explain this either.
The problem is:
[tex]sin(-\pi)+cos(5\pi)[/tex]
I have no idea what to do next. I know how the radian measure works but [tex]\pi[/tex] and [tex]5\pi[/tex] don't mean anything (to me) in regular degree's.
If anyone could give me a quick explanation on how to do these I'd really appreciate it.
