where are we now?

The thing that i really don't understands are:

  • trigonometry, the angle of elevation, depression, and some word problem that i don't understand..
  • how can I know if were going to use the sine, cosine, and tangent...the SOHCAHTOA...
  • the relation and function
That's all, the topic is really confusing..
