Answer:
Step-by-step explanation:
LHS = Sin² ∅ + Sin² ∅*tan² ∅
= Sin² ∅ [1 + tan² ∅ ] {Sec² ∅ - tan² ∅ = 1}
= Sin² ∅ *Sec² ∅
= Sin² ∅ *
= Sin² ∅ /Cos² ∅
= tan² ∅ = RHS

Answer:
Sin(t) = and
Step-by-step explanation:
The secant function is the reciprocal function of the cosine function. Therefore, given that then, if
then
.
On the other hand, if cos (t) = 1/2 ⇒ t = ±
Then, the sin() =
