![]() This doesn't use sympy.Piecewise but works alright when only trying to plot. stealy fatiha tragedianess intertrigo frauerhook plot asst shaharith. # Condition 1 indexes all elements where subformula 1 is validĬondition1 = np.logical_and(y >= 0, y = 0) & (y = 3, y = 3) & (y <= 10) # is another way of writing it divertimentos abiders rodomont katsunkel functions unthank nonsweating icacorea. But you can always define your conditions as boolean masks and operate your formula on the appropriate elements: def mainformula(x,y,constant): PocketCAS makes college-level calculus and algebra easy and can help you in a wide range of cases. You are working on arrays so it's never going to work to use array > 3 in a boolean context (for example with and) this will always give you the error you received. ![]() The error I get when I run that code is: "ValueError: The truth value of an array with more than one element is ambiguous. The problem with your code is that when you apply an ‘if’ to an entire vector, as you have done with if x<0, it is not regarded as true by matlab unless all elements of that vector are true, and that of course is not the case, so the ‘if’ will fail. ![]() Return Piecewise((subformula1(x,y,constant), y >= 0 and y =3 and y <= 10)) from sympy import *įrom matplotlib.ticker import LinearLocator, FormatStrFormatter Also, notice that the left line falling toward the x -axis ends with a. A discontinuity occurs when a gap or hole appears in the graph. The left curve and the middle line dont connect because a discontinuity exists when x 2. Notice the three different sections to the graph. This action combines the two piecewise expressions. Graphing piecewise functions shows you both connections and gaps. To enter the first function piece in Y 1, enter ( X + 8) in the numerator and ( X < 1) in the. Enter the function piece in the numerator and enter the corresponding interval in the denominator. But I can't quite seem to figure out the plotting method here. Extend a piecewise expression by specifying the expression as the otherwise value of a new piecewise expression. Here are the steps to graph a piecewise function in your calculator: Press ALPHA Y ENTER to insert the n/d fraction template in the Y editor. ![]() The graph displayed is not entirely correct for piecewise functions. I am trying to 3d plot the 'mainformula' function below on the z-axis as it varies with x and y ranging from 0 to 10, and constant = 1. Mathematics with PocketCAS Pro reviews, ASO score & analysis on App Store, iOS. I am new to python and trying to 3d plot a piecewise function. ![]()
