Let's remind ourselves of what the sine graph looks like so that we can see how many solutions we should be expecting: Therefore, from the graph of the function, we can see that we should be expecting ...

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 ...
