Question

How to find value of cosec(-1410)

Answer 1

I think this is the answer for your question

Answer 2

Answer:

cosec(−1410°)= −cosec(1410°)

= −cosec(4*360°−30°)

= cosec(30°)

Since we know that;

cosec(2*n*π−θ)= −cosecθ

So the relation shows, cosec(30°) = 2

The value of cosec(−1410°) is 2.
