Winplot is a free plotting program for Windows that can graph functions and equations in 2D and 3D, including points, parametric functions, and functions in polar, spherical, and cylindrical coordinates. It allows users to plot slope fields, approximate integrals and areas under curves, and animate changing values. Winplot is designed to illustrate mathematical concepts like slopes, areas, volumes, and vectors for students and teachers.

1. WINPLOT
An Overview

2. Presentation Outline
• What is Winplot?
• Learning about Winplot
• Gentle Introduction to Some
Winplot Options/Features

3. What is Winplot?

4. A plotting program for windows that
can graph in a 2-dimensional or 3-
dimensional plane
A Windows application that draws
graphs
–2-dimensional curves
–3-dimensional curves and
surfaces

5. • points
• functions and equations in 2 and 3
variables
• parametric functions
• functions in polar
• spherical, and cylindrical
coordinates
• slope fields of differential
equations

6. A lot more than a graphing calculator
Can approximate definite integrals
and can solve for the areas bounded
by regions and volumes made by
some solid revolutions

7. A tool to illustrate mathematical
concepts
–Slopes of lines, areas, volumes,
vectors, to name a few
–Animation that allows one to
show values as they change

8. Best of all, it’s free!
