plotReIm

Returns a plot in Cartesian coordinates by calling the function for each value of x to get the corresponding y value, and drawing a dot at the coordinates.

If the function returns a complex number, plots the real and imaginary parts separately.

Syntax

plotReIm(...funcs, max?)

Parameters

• funcs variadic

  Functions to plot.

  A function accepts an x coordinate and must return the corresponding y coordinate.

  Each function will be drawn in a different color. The imaginary part of a complex function will be drawn in the same color as the real part, but with reduced opacity.

• max optional

  If the last argument is a number, it is used as the maximum value of x.

Return value

A Plot object.

Examples

plotReIm(x => x**2 + 5*x + sqrt(-1), 6)
