> I still have no freakin clue which thing is a sin, cos or tan.
Atleast two methods I still recall:
1. Look up the SOH CAH TOA method.
2. Knowing that Sin(0) = 0 and Cos(0) = 1 can give a hint which one to use. You may know an equation should have a Sin or Cos but unsure which one so you pick the one that gives the expected results at 0 degrees. Works great for engineering type of problems.
