but many fail to make the leap on how crucial circles are for trig functions. With static graphs and equations, it's possible to get a handle on the rules of what various functions do and mean.

In a function such as sine or cosine, we could also have a translation of the form: \(y = \sin (x - a)^\circ\) where \(a\) is called the phase angle. This is when the graph of the function has ...
