Answer five questions only from this section. All questions carry equal marks. Copy and complete the table of values for y = 3 cos x, 30° ≤ x ≤ 330°

Here are the solutions to the questions from the image.

Question 6:
The function is $y = 3 \cos x$ for $30^\circ \le x \le 330^\circ$.

a) Copy and complete the table of values for $y = 3 \cos x$.

Step 1: Calculate the values of $y$ for each given $x$.

• For $x = 30^\circ$: $y = 3 \cos 30^\circ = 3 \times \frac{\sqrt{3}}{2} \approx 3 \times 0.866 = 2.598 \approx 2.6$
• For $x = 60
