Best ResponseYou've already chosen the best response.0\(\dfrac{\sin y + \tan y}{1 + \sec y} \Rightarrow \dfrac{\sin y + \tan y}{1 + \sec y} \cdot \dfrac{1  \sec y}{1  \sec y} = \dfrac{(\sin y + \tan y)(1  \sec y)}{1  \sec^2 y} \) Can you do the next step?

Best ResponseYou've already chosen the best response.1For some reason, I don't really see how this helps... better to express everything in terms of sin and cos instead... oh well.

Best ResponseYou've already chosen the best response.1\[\large \frac{\sin y \cos y + \sin y}{\cos y + 1}=\frac{(\sin y)(\cos y + 1)}{\cos y + 1}\] And now it should be easy to see.
