TeaCat is a dynamic mathematical application that aims to enable high school students to experiment with and to exercise a variety of mathematical topics. Even engineers may benefit of TeaCat for rather complex calculations, since TeaCat includes working with derivatives, integrals, systems of equations and matrices.
TeaCat allows documenting the calculations with rich text and pictures – it combines the computational engine with a well-featured word processor and graphing tools.
You can define mathematical expressions in the worksheet just as you would see them on paper and solve them both symbolical and numerical. TeaCat provides a powerful interactive graphing tool, which enables visualisation and modification of geometric objects and two dimensional graphs. You can save your documents in a TeaCat format or convert them to a PDF or image file.
