Rewrite the expression so that it is not in functional form: (sin x)/(csc x-1)

To rewrite the expression (sin x)/(csc x-1) in a form that is not in functional form, we can start by simplifying the denominator, csc x - 1.

Recall that csc x is the reciprocal of sin x, or 1/sin x. So, csc x - 1 can be simplified as:

csc x - 1 = 1/sin x - 1

Next, to eliminate the fraction, we can multiply the numerator and denominator of the expression (sin x)/(1/sin x - 1) by sin x:

(sin x)(sin x) / [1/sin x - 1]

Simplifying further, we have:

sin^2 x / [1 - sin x]

Therefore, the rewritten expression that is not in functional form is sin^2 x / (1 - sin x).
