Function Mathematica Piecewise function Oct 9, 2019 #1 confused_engineer. 39 2. TL;DR Summary I can't define a piecewise function which reads data from a table as #I have some very simple questions about how to define a periodic function in Mathematica. I've never used Mathematica before so please forgive my ignorance. What I need to do is graph and obtain the Fourier series for a 2*Pi-periodic function. My function is defined as follows: exp(x) when -pi < x < pi; cosh(pi) when x = -pi or x = pi PiecewiseExpand will also do some simplification, such as factoring and reducing a rational function; to avoid that, pass a Piecewise function directly. PlotPiecewise will not alter the formulas in a Piecewise. Note, however, that Mathematica automatically reduces x (x - 1) / (x (x - 2)) but not (x^2 - x) / (x (x - 2)).You can use Piecewise to define your piecewise functions. For example your second example could be defined as follows: f[x_] := Piecewise[{{1/(2 x^2), Abs[x] > 1}, {0, True}}] Integration: Integrate[f[x], {x, -3, 7}] yields 16/21 I have: f[x_] := Piecewise[{{x, 0 <= x < 1}, {2 - x, 1 <= x < 3}, {x - 4, 3 <= x < 4}}] Plot[f[x], {x, 0, 4}] Which produces this plot: I'm looking for a simple way to convert this into a periodic function so that this image repeats itself every 4 units, in either the positive or negative direction along the x-axis.The interpolating function returned by Interpolation [data] is set up so as to agree with data at every point explicitly specified in data.
