Curvilinear: Easy Learning Plane Analytic Geometry An Intuitively-Easy-To-Use visual interactive software, oriented to overcome the abstraction that exists in the Plane Analytic Geometry (PAG), this is a tool that makes it easy to master PAG.
Mathematics, Analytic Geometry, circle, hyperbola, parabola, ellipse, line, slope, teaching, learning,

 2)   Panageos 1
Panageos is oriented to the intensive solution of problems on Plane Analytic Geometry. The main feature of Panagoes is its power to read the user's equations and interpret them, for this reason the data input is exclusively through the keyboard.
