for all values of X for which of the following is defined, find th value of cot^2(X)- csc^2(X)

  1. MathMate

    cot^2(X)- csc^2(X)
    =(1/tan(x))2 - (1/sin(x))2
    =(cos(x)2-1)/sin(x)2
    =-sin(x)2/sin(x)2
    =-1

    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; sin(x)csc(x)=sin(x)/sin(x)=1; …

    Verify the identity. (csc(2x) - sin(2x))/cot(2x)=cos(2x) =csc(2x)/cot(2x) - sin(2x)/cot(2x) =csc(2x)/cot(2x) - cos(2x) Is this correct so far?
