(– 24, – 7)

(iii) (– 24, – 7)

Sol. The terminal arm passes through P (– 24, – 7)

∴  x = – 24 and y = – 7

 r = √(x²+y² )

∴r =√((-24)²+(-7)² )

∴r =√(576+49)

∴r =√625

∴ r = 25

Let the angle be θ

sin θ = y/r = -7/25

cosec θ = r/y = -25/7

cos θ = x/r = -24/25

sec θ = r/x = -25/24

tan θ = y/x =7/24

cot θ = x/y = 24/7
