Answer 1

`\begin{gathered} We\text{ are asked to simplify the below equation:}\frac{}{} \\ (sin^2y)/(1-cosy) \\ Using\text{ trigonometric identities we can re-write it as:} \\ (1-cos^2y)/(1-cosy) \\ The\text{ numerator is a difference of squares} \\ =\text{ }((1+cosy)(1-cosy))/((1-cosy)) \\ =\text{ 1+ cosy} \end{gathered}`

Answer: 1 + cosy
