(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
