Asked by Lindsey

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!

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

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