Okay, so this is a lame question... but I'm in a fast-track 5-week online trig course and the teacher hasn't posted any lecture notes or anything, and I wasn't able to get the book (and now couldn't get it on time even if I ordered it right away, really) because I wasn't certain I was enrolled until the first day of the course...
So I have a stupid question, but I can't find an explanation online anyways, probably because it is a stupid question...
The problem is asking me to find the cot of an angle if the cos = 7/25, and then it gave me this information: 3pi/2<0<2pi
Problem is, I've not a clue what the 3pi/2<0<2pi part means, or how/where I'm supposed to apply it.
Can anyone give me a basic, short explanation of what that stuff means and how it applies in that sort of problem? I don't need an indepth lecture or anything, just perhaps a basic definition.
Thanks in advance for answering my stupid question.
