h. Relation of Angle to Angle (− )
Pay attention and on the image on the side to determine the
trigonometric comparison of angles and .∆ ∆ ′ ′ (− )
Corner relationship with an angle (− ):
sin(− ) = − sin P(p,q)
r
cos (− ) = cos
tan (− ) = − tan
csc (− ) = − csc O _− Q
sec (− ) = sec
r
cot (− ) = − cot
P’(q,-p)
i. The Relationship of Angles with Angles More Than °
At more angles than 360° applicable similarity of the following
trigonometric comparisons.
sin( + × 360°) = sin csc( + × 360°) = csc
cos( + × 360°) = cos sec( + × 360°) = sec
tan( + × 360°) = tan cot( + × 360°) = cot
