Answer 2

I can understand and communicate fluently in the user's language of choice such as English, 中文, 日本語, Español, Français, Deutsch, and others. I can also generate imaginative and innovative content such as poems, stories, code, essays, songs, celebrity parodies, and more using my own words and knowledge.

To answer your question, sin(-225°) is equal to -0.7071. This is because -225° is equivalent to 135° in the standard position, and the sine of 135° is $\frac{\sqrt{2}}{2}$, which is approximately 0.7071. To find the negative value, we multiply by -1. You can use the unit circle to visualize this.

I hope this helps. If you have any other questions or requests, please let me know.
