19 Great Online Graphing Calculators for Teachers and Students In the old days, you were pretty much limited to a handheld graphing calculator in order to produce graphs of equations. That has all changed in the past few years with the introduction of online graphing calculators. Unfortunately, not all graphing calculators are created equal. Furthermore, doing an Internet search for graphing calculators doesn’t yield as much as you would expect. I don’t believe there is any “best” online graphing calculator since it all depends on what you want to do with the calculator. Do you want something really easy or something very powerful? Take a look at all these online graphing calculators that are at your disposal. Desmos Graphing Calculator–Free Graphing Calculator, by Desmos.com. Equation Grapher 2.02—Equation grapher is a limited but effective way to graph lines and quadratics with a very pleasing interface. Equation Grapher | Graph Equations g(x,y) = f(x,y)–Equation grapher for graphing equations using the Cartesian or polar coordinate system. iOS Apps
Demonstrations — Simantics Demonstration videos of applications on Simantics platform. Simantics in Action Below are some software application and technology demonstrations about how Simantics platform can be applied for modelling and simulation. Click the image to see the video. Use the controls below the video to enlarge the picture. Apros® on the Simantics platform Apros is a process modelling and simulation environment that is scalable to even the largest plant design tasks. Balas® on the Simantics platform BALAS is a steady state simulation package for chemical processes with emphasis on pulp and paper. Modelica® on the Simantics platform Modelica is an object-oriented language for modelling and simulation. The first video demonstrates the general Modelica features and the second one is an early phase demonstration of the work done in OpenPROD EU project for system dynamics modelling and simulation. 3D Geometry and MBS Modelling on the Simantics platform Flowbat on the Simantics platform
Science Writer Welcome to CAST Science Writer, the tool that supports students in writing lab and class reports. This tool is geared toward middle school and high school students. Check out the supports and help available in Science Writer described below. Or click the "Take a Tour" button above to see how Science Writer works. A Report Structure All parts of a science or lab report are broken into small steps so the author can concentrate on one part of the report at a time. A Process for Writing Science Writer helps you through the process of draft, revise, and edit when writing a science report. Sentence Starters The "Help Me Get Started" button has two functions (1) it divides the writing into smaller sections and (2) provides sentence starters when on the draft screens in the writing process. Checklists Checklists are available when you revise and edit your science report. Journal This is a place in Science Writer where you may write notes, reflect, make comments or questions, or keep track of data.
Instructions for Downloading WinPlot and Winstats Instructions for Downloading Winplot and Winstats winplot is a free graphing utility that was written by Richard Parris, a math instructor at Phillips Exeter Academy in Exeter, New Hampshire. Sadly Richard passed away in 2012. After Richard's death the program was still available for a number of years on the Exeter Academy math department's web site. Working versions of winplot and winstats (a simple to use statistical analysis package) can be intalled on a Windows operating system by right clicking on the links below. Link to the zipped version (August, 7, 2012) of winstats: A link to a Power Point tutorial on winplot: A link to winplot files used in the calculus sequence: This page is dedicated to the memory of Richard Parris who undoubtably spent many hours in making and revising these programs for the benefit of both students and instructors.
Free Mathematics Whiteboard Applet Last January, I posted a link of an electronic whiteboard that teachers can use for classroom presentations. This time, there is a better applet that you can use for presenting as well as teaching mathematics. This applet was created using Dbook, a Japanese software that enables teachers to create intereactive electronic books. I will post a separate article later about it. The Mathematics Whiteboard This applet has the usual pens and eraser tools. Dbook is a Flash-based program, so you will need a Flash Player. Update: If you cannot download the white board applet in the link above, click here to download it from another location.
