👉 Learn how to graph the square root function. Like other functions, to graph the square root function, we first graph the parent function (i.e., the graph of f(x) = square root of x) and then we ...

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 ...

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 ...

Abstract: To solve the complex tasks of digital signal processing, it is important to use effective spectrum transformation procedures. This article discusses the operator of spectrum transformation ...
