This problem has three parts. A part may be open if it is correct or if it is the first incorrect part. Clicking on the heading for a part toggles whether it is displayed.

Part 1

In this multi-part problem, we will use algebra to verify the identity

$\displaystyle \frac{ \sin(t) }{ 1-\cos(t) } = \frac{ 1+\cos(t) }{ \sin(t) }.$

First, using algebra we may rewrite the equation above as $\displaystyle \sin(t) = \left( \frac{1+\cos(t)}{\sin(t)} \right) \cdot \Big($ $\Big)$ .
