Choose the correct alternative answer for the following questions.

sinθ cosecθ = ?

A. 1

B. 0

C. 𝟏𝟐

D. √𝟐

Solution

The correct answer is A. 1.

We know that:

sinθ = 1/cosecθ

Multiplying both sides by cosecθ, we get:

sinθ cosecθ = 1

Therefore, sinθ cosecθ = 1.

Explanation:_

We know that:

cosecθ = 1/sinθ

Therefore,

sinθ cosecθ = sinθ × 1/sinθ = 1

Hence, the correct answer is option A: 1.
