Express \(sin\,x-\sqrt{3}\,cos\,x\) in the form \(k\,sin(x+a)\) where \(k\gt 0\) and \(0\lt a \lt 2\pi.\) Show answer Note that this solution should use radians throughout.
B: Solving Trig equations 1. Rearrange the equation to make the trig ratio (usually sin, cos or tan) the subject e.g. sin x + 1 = 0 =) sin x = ˇ 1 p 2cos(x + 5 ˇ 6) 1 = 0 =) cos(x + 5 ˇ 6) = 1 p 2 2. Find the basic angle that satis es this ratio {this may involve looking at the angles in the two special triangles or looking at the ...
