Question

Use the given information to find the exact value of the expression:

Find cos(2, q),csc q =
q lies in quadrant II

-7/25
24/25
7/25
-24/25

Answer 1

I'm confused by the notation.

You can't have cos(2,q). The cosine functions yields an angle given the adjacent and hypotenuse.

Can you please clarify your question?

Answer 2

Find cos(2,è),csc è = è lies in quadrant II

I didn't have a theta sign so I used q

-7/25
24/25
7/25
-24/25

Answer 3

You can just use x instead of theta.

cos(2x)csc(x)

Is this correct? We are multiplying cosine of 2 theta by cosecant of theta?

Answer 4

yes

Answer 5

They have to give you some number to solve this.

Are you sure it's not find cos(2x) given csc(x) = some number they give you?

Answer 6

exact question is :

Use the given information to find the exact value of the expression

Find cos(2,x),csc x= x lies in quadrant II

-7/25
24/25
7/25
-24/25

Answer 7

I still don't fully understand the notation and the commas. Sorry, maybe someone else can help you.

Answer 8

thanks anyway
