(a) Copy and complete the table of values for \(y = 1 - 4\cos x\). x 0^\circ 30^\circ 60^\circ 90^\circ 120^\circ 150^\circ 180^\circ 210^\circ 240^\circ 270^\circ 300^\circ y -3.0 1.0 4.5 -1.0 (b) Using a scale of 2cm to 30^\circ on the x- axis and 2cm to 1 unit on the y- axis, draw the graph of \(y = 1 - 4\cos x\) for \(0^\circ \leq x \leq 360^\circ\). (c) Use the graph to : (i) solve the equation \(1 - 4\cos x = 0\) ; (ii) find the value of y when x = 105^\circ ; (iii) find x when y = 1.5.
