[en] Trigonometry has an important place in mathematical Belgian education. At grade 10, students have to go from trigonometric numbers, with degrees and in triangles, to trigonometric functions, with radians and in the unit circle. This passage could be quite uneasy. To lighten this field, we analyzed the history of trigonometry and the Belgian programs and manuals. We are now questioning teachers and students.
Afterwards, we plan to build a lesson using dynamic geometry to illustrate this passage.
