I just deleted my post but.... I think I was righter with the

.5 Cos ^ 2

Cscs cancel leaving you with Cos^2 / 1 + 1

Steps:

csc(x) cos^2(x)/ 1+csc(x)

(1/sinx)(cos^2x) / [1+(1/sinx)]

=(cos^2x/sinx)/[(sinx+1)/sinx)] - First part, multiply. Cos on top, sin on bottom. 2nd part, common base.

=(Cos^2x/sinx)x(sinx/sinx+1) -Multiply by reciprocal. First sinx on bottom, cancels 2nd sinx (which is on top)

=Cos^2/(Sinx+1)
