Sure, I can help you with that.
Since sine is an odd function, sin(-t) = -sin(t). Therefore, if sin(t) = 0.57, then sin(-t) = -0.57 = -0.5396320487339692.
Here is the explanation:
* **Odd function:** A function is said to be odd if the negative of its argument results in the negative of its value. For example, the function f(x) = x^2 is odd, because f(-x) = (-x)^2 = x^2, which is the negative of f(x).
* **Sine function:** The sine function is an odd function. This means that sin(-t) = -sin(t).
Therefore, if sin(t) = 0.57, then sin(-t) = -0.57 = -0.5396320487339692.
I hope this helps! Let me know if you have any other questions.
