Trigo identities
Pythagorean Identity
Double angles
Negative angles
θ is negative when the angle rotates in a
clockwise direction (I-IV-III-II)
cos (-θ) is positive because cos θ = x
In Quadrant IV, x is positive.
sin θ, cos θ and tan θ value is the same with their corresponding acute angle
Sign at 4 Quadrant
