Question 1 Report
(a) Copy and complete the table of values for \(y = 2\cos x + 3\sin x\) for \(0^\circ \geq x \geq 360^\circ\)
| x | \(0^\circ\) | \(60^\circ\) | \(120^\circ\) | \(180^\circ\) | \(240^\circ\) | \(300^\circ\) | \(360^\circ\) |
| y | 2.0 | - 3.6 |
(b) Using a scale of 2cm to \(60^\circ\) on the x-axis and 2cm to 1 unit in the y-axis, draw the graph of \(y = 2\cos x + 3\sin x\) for \(0^\circ \geq 360^\circ\)
(c) Using the graph,
(i) Solve \(2\cos x + 3\sin x = -1\)
(ii) Find, correct to one decimal place, the value of y when \(x = 342^\circ\)
