(5, – 12)

(ii) (5, – 12)
Sol. The terminal arm passes through P (5, – 12)
∴  x = 5 and y = – 12

r= √(x2+y2 )
∴r=√(52+ (-12)2 )
∴r=√(25+144)
∴r=√169
∴ r = 13
Let the angle be θ
sin θ = y/r = -12/13
cosec θ = r/y = -13/12
cos θ = x/r = 5/13
sec θ = r/x = 13/5
tan θ = y/x =-12/5

cot θ = x/y = -5/12
