(– 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
