Find the trigonometric functions of :

270°

#### 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

Is there an error in this question or solution?
