MadCalc

Designed for math students, MadCalc is a straightforward and practical tool capable of plotting multiple operations at the same time. It can also be used by teachers who want to show students how graphs work by creating and printing handouts.

The program supports rectangular, parametric and polar equations. It comes bundled in a simple interface that doesn't stand out as far as appearance is concerned. However, it has a well-organized layout that makes it easy to enter equation data.

Up to eight equations can be entered, and you can modify the range of the coordinates by specifying the minimum and maximum X and Y. The plot is generated as soon as you press the "Plot" button.

Rectangular plots are created by default but you can switch to parametric or polar mode with ease, as well as zoom in and out. If you're interested in configuring some settings, you can head over to the options panel and pick other colors for each graph, the background and axis.

What's more, you can hide axes and set a different default plotting mode. Settings can be restored to their original values anytime. To be able to create and print handouts, you just have to export the graph and put together a PNG or BMP image file.

The application doesn't need to be installed, so you can keep it saved in your collection of portable software and fire it up whenever you need to generate plots. Also, it can be moved to a USB flash drive to effortlessly run it on any machine without installation.

Everything worked smoothly on the latest Windows edition in our tests. Unsurprisingly, the tool used minimum system resources and generated plots instantly.

Taking everything into account, MadCalc may not have comprehensive features but it delivers an effective solution for creating plots based on multiple equations at once. It can be used with ease by both math students and teachers.
