An angle θ satisfies the relation csc θ cos θ = -1.

A) Use the definition of the reciprocal trigonometric ratios to express the left side in terms of sin θ and cos θ.

B) What is the relation between sin θ and cos θ for this angle?

C) Determine two possible values for θ.

- Please help me with this question, I have no clue where to start as my teacher never taught us something like this!

  1. cscθ cosθ = -1
    1/sinθ cosθ = -1
    cosθ/sinθ = -1

    as with any angle,
    cos^2θ + sin^2θ = 1
    In this case,
    cosθ = -sinθ

    tanθ = -1
    θ = 3π/4 or 7π/4

    No idea at all? Hmmm. I cannot believe that the question was assigned, yet the material never taught!!!???

    And have you never heard of google?

    Hello all, In our math class, we are practicing the trigonometric identities (i.e., sin^2(x)+cos^2(x)=1 or cot(x)=cos(x)/sin(x). Now, we are working on proofs that two sides of an equation are equal (for example, sin(x)*csc(x)=1;

    I need to prove that the following is true. Thanks. csc^2(A/2)=2secA/secA-1 Right Side=(2/cosA)/(1/cosA - 1) = (2/cosA)/[(1-cosA)/cosA] =2/cosA x (cosA)/(1-cosA) =2/(1-cosA) now recall cos 2X = cos^2 X - sin^2 X and we could say
