Question

solve cosec(-390°) plss​

Answer 1

Explanation:

Since the cosecant function is the reciprocal of the sine function, we can write sin 390° as 1/cosec(390°). The value of cosec 390° is equal to 2.

Answer 2

Answer:

cosec 390° = 2

Explanation:

cosec(360 °+θ) = cosec θ

cosec390°= cosec(360°+30 )

cosec390° = cosec30°

cosec30° = 2

therefore,

cosec 390° = 2
