I often use Graph to plot 2D function (implicit ones included). It's free, and pretty easy to use, I may be inclined to say that it's also user-friendly. And I just love it.arunbg said:Can anybody give me links to download software that can plot implicit functions like x^2 + xy =9 etc.
I have searched the net but all that i have found are shareware demos that expire after a period.I am sure there are freeware plotters of this kind but can't find any.
An implicit function grapher is a tool used in mathematics to graph equations that cannot be easily solved for a specific variable. These equations typically involve multiple variables and may not have a clear functional form.
An implicit function grapher uses numerical methods, such as the Newton-Raphson method or the bisection method, to approximate the points on the graph of an equation. It iteratively solves the equation for different values of the variables and plots the resulting points on a graph.
An implicit function grapher can graph any equation that can be written in the form f(x,y) = 0, where f is a function of two or more variables. This includes equations with trigonometric, exponential, and logarithmic functions, as well as polynomial and rational functions.
An implicit function grapher provides accurate approximations of the graph of an equation, but it is not exact. The accuracy depends on the chosen numerical method, the number of iterations, and the precision of the input values. It is important to note that the graph is an approximation, not the exact solution.
An implicit function grapher is limited by the complexity of the equation and the chosen numerical method. Equations with multiple solutions, discontinuities, or singularities may be difficult to graph accurately. Additionally, the graph may not be able to provide a complete representation of the equation, as it is only a numerical approximation.
