Question

cot(570 )+sin(-330°)/
tan(-210°)+cosec (750)​

Answer 1

Answer:

Please make as brainlist answer

Step-by-step explanation:

given, cosec 750∘

=cosec(2×360∘+30∘)

=cosec (30∘) since cosec (2nπ+θ)=cscθ

=2

Answer 2

Step-by-step explanation:

cot(570 )+sin(-330°)/

tan(-210°)+cosec (750)

Answer 3

Step-by-step explanation:

cot(570 )+sin(-330°)/

tan(-210°)+cosec (750)
