Question

Find the trigonometric function of :

0°

Answer 1

Angle of measure 0° -

Let the measure of the ∠XOA in standard position be 0°.

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

Hence, x = 1 and y = 0.

 ∴ sin 0° = y = 0,

cos 0° = x = 1,

tan 0° = `y/x = 0/1` = 0,

cot 0° = `x/y=1/0`.....(which is not defined)

`"cosec"  0^circ = 1/y = 1/0` ....(which is not defined)

sec 0° = `1/x = 1/1 = 1`
