Question

find the value of cosec(-480°)​

Answer 1

Answer:

{cosec(-thita)=cosec thita}

cosec(-480⁰)=cosec(360⁰+180⁰)=cosec 180⁰=0

Answer 2

Answer:

2/√3

Step-by-step explanation:

Sin=1/cosec

Therefore, Cosec(-480°)= 1/-Sin120°

=1/ - ( -√3/2)

=1/√3/2

=2/√3

Hence, Cosec(-480)=2/√3

Good luck.
