Solve \(\sqrt 3 \cos x + \sin x = \sqrt 2\), for \(0 \le x \le 2\pi\). First of all we need to put \(\sqrt 3 \cos x + \sin x\) into the form \(k\cos (x - \alpha ...
An understanding of the three trigonometric ratios and how to change the subject of a formula is essential ... \(a\) and \(h\) to give cos(49) = 11/\(x\). To remove \(x\) from the denominator ...
