Students who desire a teaching assistantship require very high grades in the TOEFL, and Easy TOEFL Grammar helps to achieve this objective.

Easy TOEFL Grammar is an EduVirtualLab resulting from the experience of an international team of English-language instructors in several countries, who are dedicated to the preparation of students wanting to go to universities in English speaking countries and who are required to take an English proficiency test (TOEFL, Aligu, Michigan, etc) in order to be admitted and even to be awarded a teaching assistantship in those institutions.

EconoModeler

EconoModeler :   Analytic Geometry for Economics Applications

Analytic Geometry for Economists and for Economic Analysis

Economic Models - Mathematical Economics

EconoModeler  

This is an Analytic Geometry EduVirtualLab for Computer Assisted Teaching and Learning with applications to Economics.

EconoModeler is also used in professional applications.   

As it can be seen with EconoModeler just by clicking and dragging the mouse the user can very easily and very quickly design Points, Lines, Circles, Ellipses, Parabolas, Hyperbolas and Circular Arcs. As the user makes the curves on the black-color region, the corresponding coordinates, equations and pertinent data are shown on the left side text column.    

At any moment the position of the origin of coordinates can be placed wherever the user needs it to be (ideal for those applications where only the first quadrant is used). The names of the X and Y axes can be changed at will. The black-color region can be printed (on a black background so that color ink is saved). The left side column with results may also  be printed alone. EconoModeler exists in English and in Castellano.

EconoModeler calculates and reports the following intersections:  line-line, line-circle, line-parabola, line-elipse, line-Hyperbola, parabola-parabola. 

The user's imagination is the limit.
