The expression as is when evaluated according to the BEDMAS rules would be equal to:
sin<sup>2</sup>θ - cosθ
since the division is done before the subtraction.
The expression should have been written
sin<sup>2</sup>θ/(1-cosθ)
in which case
= (1-cos<sup>2</sup>θ)/(1-cosθ)
=(1+cosθ)(1-cosθ)/(1-cosθ)
=1+cosθ
if θ≠2nπ, where n is an integer.
