Graphs of Trigonometric Functions?! C2

My maths teacher who taught this is terrible. We have homework due in tomorrow (like a mixed exercise from the book) and I can't do any of it, not even the first few questions. She went through very briefly positive and negative angles and the CAST diagram in like 20 minutes, then left the lesson during the graphs section...So I basically have no knowledge on this topic...Can anyone help?

I KNOW NOTHING!

Hi;

Can you post a question from your homework?

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

hi Beverrrn

Take a look at this page especially (but there's loads of backup material on the connected trig. pages.)
