Question

Verify the basic identity. What is the domain of validity?

cotθ = cosθ cscθ

Answer 1

Are you trying to prove the identity?

Answer 2

Yes and Domain of validity?

Answer 3

cotx=cosxcscx

Replace cscx with an equivalent expression (1)/(sin(x)) using the fundamental identities.
(cosx)/(sin(x))

Rewrite the expression using the (cosx)/(sinx)=cotx identity.

Answer 4

thats the answer

Answer 5

To prove the identity yes. I just don't understand what you mean by domain of validity.

Answer 6

whaT YOU THINK IT Can be ?

Answer 7

This is for trig, correct?

Answer 8

yes

Answer 9

I've never heard of domain of validity. Perhaps the question is asking what the domain is??

Answer 10

it said Domain of validity

Answer 11

Every pi interval then. so:
0< theta-pi (n)<pi.

Answer 12

so im PUT THAT AS ANSWER

Answer 13

It should be correct.

Answer 14

THANKS MAN . I MIGHT NEED SOME HELP. CAN I MESSAGE IF I NEED MORE HELP

Answer 15

Sure
