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.

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

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?

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?
