Trigonometric functions

The sine function

The cosine function


The possibility that pupils can interact with trigonometric functions should improve the comprehension of their characteristics and properties.  In these activities it is aimed on one hand, that the teacher has at their disposal a tool to illustrate their explications when they define the trigonometric functions, and on the other hand, the pupils can intervene changing parameters and watching the results.   

The ease with which the parameters which define each activity can be modified, allows numerous exercises to be made up, adapted to the objectives of each teacher at each level and the needs of each pupil.
