Verify the trigonometric identity. Please show all steps. tanx-cotx/tanx+cotx=sin^2x-cos^2x

  • trig -

    Hint:
    When there is a mixture of tan, sin and cos, use identities to convert everything into sin and cos, and simplify. This usually works, especially if the right-hand side is in sin and cosine.

    For your information,
    tan(x)=sin(x)/cos(x)
    cot(x)=cos(x)/sin(x)
