What are the examples of Fourier transform?
An example application of the Fourier transform is determining the constituent pitches in a musical waveform. This image is the result of applying a Constant-Q transform (a Fourier-related transform) to the waveform of a C major piano chord.
What is one real world example of a piecewise function?
A simple example of the need for piecewise functions occurs when you lease a car. To lease a car is to essentially rent the car for a period of time. You lease a car for four years for with a mile limit of miles. This limit means that if you drive more than miles, you will have to pay a fee.
What is the formula of piecewise function?
A piecewise function is a function built from pieces of different functions over different intervals. For example, we can make a piecewise function f(x) where f(x) = -9 when -9 < x ≤ -5, f(x) = 6 when -5 < x ≤ -1, and f(x) = -7 when -1.
