- Let xxx satisfy sin(x)=2−2\sin(x) = \sqrt{2 - \sqrt{2}}sin(x)=2−2. What is tan(x)\tan(x)tan(x)? (Hint: Use an identity to find cos(x)\cos(x)cos(x) first.)
- If tan(x)=sin(x)cos(x)\tan(x) = \frac{\sin(x)}{\cos(x)}tan(x)=cos(x)sin(x), then what happens when cos(x)=0\cos(x) = 0cos(x)=0?
- What is sin(x)tan(x)\frac{\sin(x)}{\tan(x)}tan(x)sin(x)?
