Use the properties of logarithms and trigonometric identities to verify the identity.

ln|cot x| = ln|cos x| - ln|sin x|

I have no idea where to begin with this one... your help is appreciated!

  • Trigonometry -

    RS = ln (|cosx|/|sinx|)
    = ln |cot x|
    = LS

    using cot Ø = cosØ/sinØ
    and
    log A - logB = log(A/B)
