Question
**2.** You are asked to check a classmate's work and give quality feedback. Your classmate said that \( \cos 30 = \frac{1}{2} \). What feedback would you give?

---

Explain that \(\cos 30^\circ \) does not equal \(\frac{1}{2}\). Instead, \(\cos 30^\circ \) equals \(\frac{\sqrt{3}}{2}\). Encourage the classmate to review the values for trigonometric functions of common angles, such as 30°, 45°, and 60°, to avoid similar mistakes in the future.
