  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?

  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?
