In a self-diagnosis situation, self-monitoring can help you determine any symptoms or behaviors, so you can pass them on to a doctor. Many have no real idea of what their behaviors or triggers are. Self-monitoring can help you gather that information first before meeting with a professional.
Note.... sin (-θ) = -sin(θ)
And tanθ =√15 / 15 = 1 / √15
So
-sin (θ) = -1/4 ⇒ sin (θ) = 1/4
And
tan (θ) = sin (θ) / cos(θ) rearrange as
cos (θ) = sin (θ) / tan (θ) = (1/4) / (1/ √15) = (1/4) * (√15 / 1) = √15 / 4 ⇒ C
