Question

if cosβ = 0.5 find possible values for sinβ and tanβ giving your answer in exact form

Answer 1

→ Cosβ = 1/2

→ Cosβ = Cos(π/3)

So, β = π/3

Hence,

tanβ = tan(π/3) = √3

Sinβ = Sin(π/3) = √3/2

Hope it helps...

Answer 2

Step-by-step explanation:

If cosβ = 0.5 = 1/2

Then β= 60°

So sinβ = sin 60° =√3/2

and tanβ = tan 60° = √3
