#### Problem Statements:
(a) **Given:** \( \sin t = 0.31 \)
- **Find:** \( \sin(-t) \)
- **Answer:** \( \sin(-t) = \) [Input box with X indicating incorrect answer]
(b) **Given:** \( \sin \phi = -0.44 \)
- **Find:** \( \sin(-\phi) \)
- **Answer:** \( \sin(-\phi) = \) [Blank input box]
(c) **Given:** \( \cos \alpha = 0.26 \)
- **Find:** \( \cos(-\alpha) \)
- **Answer:** \( \cos(-\alpha) = \) [Blank input box]
(d) **Given:** \( \cos s = -0.59 \)
- **Find:** \( \cos(-s) \)
- **Answer:** \( \cos(-s) = \) [Blank input box]

These exercises aim to practice the properties of sine and cosine functions, specifically focusing on their symmetry properties:
- The sine function is odd, meaning \( \sin(-x) = -\sin(x) \).
- The cosine function is even, meaning \( \cos(-x) = \cos(x) \).
Be sure to use these properties when solving the problems.](https://content.bartleby.com/qna-images/question/f7e29160-8b58-485e-8a5b-b6eaf19fb950/34583f27-5971-4aa2-bda1-898e1fd47aac/ejxm65o_thumbnail.png)
