(0.5)\) \(x^\circ = 30^\circ\) So we know that the first solution is 30˚ as previously predicted from the graph. To get the other solution, we need to go back to our quadrants and use the ...
we need to use the rule in the 2nd quadrant. From the graph of the function, we can see that we should be expecting 2 solutions: 1 solution between \(180^\circ\) and \(270^\circ\) and the other ...
