How would I evaluate this?

(1-cos^2(x))/(1-cos(x))

 

\(\begin{array}{|rcll|} \hline && \frac{1-cos^2(x)} { 1-cos(x) } \\ &&& \Big( 1-cos(x) \Big) \Big(1+cos(x) \Big) = 1-cos^2(x) \\ &=& \frac{\Big( 1-cos(x) \Big) \Big(1+cos(x) \Big)} { \Big(1-cos(x) \Big) } \\ &=& 1+cos(x) \\ \hline \end{array} \)
