What do you think the graph of \(y = \cos 2x^\circ\) would look like? amplitude = 1, so the distance between the maximum and minimum values is 2 number of waves = 2 (period is 360˚ ÷ 2 = 180 ...

Watch this video to learn about solving trigonometric equations. Let's remind ourselves of what the sine graph looks like so that we can see how many solutions we should be expecting: Therefore ...

The last one is to discard an equation from the graph. Mathematics on this graph isn’t limited to algebraic expressions. You can also plot graphs for trigonometric equations (equations that use ...
