1.236 FAQ-1010 How to create an implicit function plot?

Last Update: 5/16/2019

To create a plot of an implicit function, you will need to create an implicit function and then simulate this function. For example, to plot function

$x^2+(y-\sqrt[3]{x^2})^2=1$

Create an implicit user-defined function by Tools: Fitting Function Organizer.
1. Create a new user-defined function under "User Defined" category.
2. Define the function as follow:
  - Function Name = Heart
  - Function Model = Implicit.
  - Variables = x,y
  - Function From = Equation
  - Function = f=x*x+(y-(x*x)^(1/3))^2-r^2.
    Note: You can also refer to function "Circle" under Implicit category for how to define an implicit function.
3. Click Save button to save it.
Click Simulate button to create a plot of this function.
