Let's remind ourselves of what the sine graph looks like so that we can see ... Therefore since the trig equation we are solving is sin and it is positive (0.5), then we are in the 1st and 2nd ...

Many students think they've solved a trig equation ... 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 ...

You can also plot graphs for trigonometric equations (equations that use sine ... and even plot graphs for various kinds of functions like modulus, absolute values, and the greatest integer ...
