Work Step by Step

1. Plot the point $(0,-2)$ (red) as shown in the figure. 2. Connect the point with the origin, and angle $\theta$ is indicated. 3. We have $sin\theta=-1$ 4. We have $cos\theta=0$ 5. We have $tan\theta$ as undefined. 6. We have $cot\theta=0$ 7. We have $sec\theta$ as undefined. 8. We have $csc\theta=-1$
