Learn how to write the trigonometric equation of a graph step by step by identifying the key features that shape sine and ...

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 ...

Swept sine waves let you test a device over a wide frequency range. To implement a swept sine wave with a multifunction data-acquisition card, you need to generate the data points and send them to the ...
