Transcribed Image Text:### Trigonometric Values and Inverse Trigonometry Practice
Use a straight edge to make a grid matching the size shown and put only your final answer in the boxes. For clarity, you may show the given expression with an equal sign before your answer. Use "undefined" rather than DNE if the ratio gives zero in the denominator. Give any angle answers in radians (real numbers).
#### Give exact, simplified answers:
| Trigonometric Expression | Result |
|--------------------------|--------|
| \(\sin \frac{3\pi}{2}\) | |
| \(\sin^{-1}\left(-\frac{\sqrt{3}}{2}\right)\) | |
| \(\cos 0\) | |
| \(\tan \pi\) | |
| \(\tan 90^\circ\) | |
| \(\tan^{-1}(1)\) | |
| \(\csc \frac{\pi}{4}\) | |
| \(\cos^{-1}\left(-\frac{1}{2}\right)\) | |
| \(\sec 90^\circ\) | |
| \(\cos \frac{11\pi}{12}\) | |
| \(\sin \frac{5\pi}{7}\) | |
| \(\sin 0\) | |
| \(\sin 240^\circ\) | |
| \(\tan^{-1}\left(\frac{\sqrt{3}}{3}\right)\) | |
| \(\cos 45^\circ\) | |
#### Instructions for Students:
- Carefully draw a grid with matching row and column sizes.
- Evaluate each trigonometric expression precisely.
- Simplify your answers and write them in the respective boxes.
- Remember to write angle measures in radians when applicable.
- If any ratio results in division by zero, use the term "undefined."
This exercise is designed to reinforce your understanding of both standard trigonometric values and inverse trigonometric functions.
