Solve the equation \(4\sin x^\circ - 3 = 0\), where \(0 \le x \textless 360\). From the graph of the function, we can see that we should be expecting 2 solutions: 1 solution between \(0^\circ\) and ...
The double angle formulae are: \(\sin 2A = 2\sin A\cos A\) \(\cos 2A = {\cos ^2}A - {\sin ^2}A\) \(= 2{\cos ^2}A - 1\) \(= 1 - 2{\sin ^2}A\) Solve the equation \(5 ...
