(– 2, – 3)

(vi) (– 2, – 3)

Sol. The terminal arm passes through P (– 2, – 3)

∴  x = – 2 and y = – 3     

r = √(x²+y² )

∴ r =√((-2)²+(-3)² )

∴ r =√(4+9)

∴ r =√13

Let the angle be θ

sin θ = y/r = -3/√13

cosec θ = r/y = -√13/3

cos θ = x/r = -2/√13

sec θ = r/x = -√13/2      

tan θ = y/x =3/2

cot θ = x/y = 2/3
