cos x cot = csc  sin

What are we doing?
Solving ?
or
proving it is an identity?
BTW, you have to put the x for all the trig functions
that is,
cosx cotx = cscx  sinx
Let's see if it is an identity...
LS = cosx (cosx/sinx
= cos^2 x/sinx
RS = 1/sinx  sinx
= (1  sin^2 x)/sin
= cos^2 x/sinx
= LS
ahh, it is an identity 
Cos (cos/sin)= cos^2/sin = (1  sin^2x)/sin
1/sin sin^2/sin = csc x sin x
