I have had trouble solving this problem.
Beginning with the trigonmetic identity
cos^2(phi)+ sin^2(phi) = 1
show that the trigonmetric identity
cot(phi) + csc(phi) = sin(phi)/ 1 - cos(phi) holds
any help would be much appreciated.
sin(phi)/ 1 or 1/sin(phi) ?

Here is a better illustration of it.
Well, youre told to begin with the trig identity, so start there.
Now divide by sin(φ)(1−cos(φ)) and youll get the answer.
