👉 Learn how to graph a sine function. To graph a sine function, we first determine the amplitude (the maximum point on the ...

👉 Learn the basics to graphing sine and cosine functions. The sine graph is a sinusoidal graph with x-intercepts at x = ...

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 been ...

Many students think they've solved a trig equation when they get one answer (one size of angle \(x^\circ\)). However there's often more than one answer expected so be aware of this. Let's remind ...
