TRIGONOMETRY!

For me I felt bombarded with all the data we had to memorize. Here's what I don't fully understand.

-How do we tell when we has to us Sin or Cos .
-"Line of depression" to "rise" ... or something like that
-How do we take a word problem and put it into a diagram

I get so lost with all this information, I found it was too much and too complicated because everything is linked together.
I hope that helps ....
