Solution

Angle of measure 270° :

Let m∠XOA = 270°

Its terminal arm (ray OA) intersects the standard unit circle at P(0, – 1).

∴ x = 0 and y = – 1

sin 270° = y = – 1

cos 270° = x = 0

tan 270° = `y/x`

= `-1/0`, which is not defined

cosec 270° = `1/y`

= `1/(-1)`

= – 1

sec 270° = `1/x`

= `1/0`, which is not defined

cot 270° = `x/y = 0/(-1)` = 0
