# In the Given Figure, ∠ Pqr = 90° , ∠ Pqs = 90° , ∠ Prq = α and ∠ Qps = θ Write the Following Trigonometric Ratios. (I) Sin α , Cos α , Tan α (Ii) Sin θ , Cos θ , Tan θ - Geometry

Sum

In the given figure, angle PQR = 90° , angle PQS = 90° , angle PRQ = α  and angle QPS = θ   Write the following trigonometric ratios.
(i) sin α, cos α  , tan α
(ii) sin θ , cos θ , tan θ

#### Solution

(i) sin α = "Opposite Side Of ∠ PRQ"/"Hypotenuse" = "PQ"/"PR"

Cos α = "Adjacent side of ∠ PRQ"/"Hypotenuse" = "RQ"/"PR"

tan α = "Opposite side of ∠PRQ"/"Adjacent side of ∠PRQ" = "PQ"/"RQ"

(ii) sin θ , cos θ , tan θ
