Archimedes Grapher is a kind of powerful and convenient tool software which supports functional graph plotting, numerical calculation, unit conversion, and slide show.

It can plot all kinds of graphs (functional graphs, table graphs, polar equation, parameter equation, inequation and etc.), implement all kinds of calculations (multivariable scientific calculation, generating numerical table, finding point of intersection, tangent/normal and derivative), provides a tool for unit conversion (supports the conversion of more than 200 units in 12 classes), and made functional graphs into slides for the purpose of teaching demonstration.
