Hello, I'm a sophomore in high school that started Algebra 2 & Trigonometry this year, so I am a first year student of trig with little experience with it. I do not understand the trigonometric identities. I have a list of trigonometric identities in my notes, but I don't know how to use them in order to solve a problem.
Example from my homework:
Solve for values of between 0o and 90o.
, find Sin
Where exactly would I start with this equation? I was thinking I would use the Pythagorean identity "Sin2
=1"; however, I am not sure.
How would I solve this problem if the value of
is between 180o
. What about between 270o
