Which identity could be the missing step to verify the identity (cos theta) (csc theta) = cot theta

(cosx) (cscx) = cotx

cscx = 1/sinx

(cosx) (1/sinx) = (cosx/sinx)

cosx/sinx = cotx

Basically, I noticed that cscx is equivalent to 1 divided by sinx, and then multiplied that fraction by cosx, which got me cosx/sinx. Your quotient identities will tell you that cosx/sinx = cotx
