(–1 , √3)

(iv) (–1 , √3)

Sol. The terminal arm passes through P (–1, √ 3)

∴  x = – 1 and y = √3

r = √(x²+y² )

∴ r =√((-1)²+(√3)² )

∴ r =√(1+3)

∴ r =√4

∴  r = 2

Let the angle be θ

sin θ = y/r = √3/2

cosec θ = r/y = 2/√3

cos θ = x/r = -1/2

sec θ = r/x = -2

tan θ = y/x =-√3

cot θ = x/y = -1/√3
