Graphs of Sine and Cosine 1.2 An applet illustrating how the graphs of sine and cosine are related to the unit circle. Transformations of Functions 1.3 An applet illustrating how transformations ...

so let’s say it’s like a sine curve. Sine curves arose in early astronomy to describe one dimension of something moving in a circular way—for instance, the up-and-down aspect of the motion ...

However there's often more than one answer expected so be aware of this. Let's remind ourselves of what the sine graph looks like so that we can see how many solutions we should be expecting ...

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 ...
