| Summary: | Trigonometry is always associated with visual representations of triangles. But trigonometric learning in schools introduces visual representations of trigonometry only at the beginning of learning. This project aims to formulate a visualisation of trigonometric operations on sines and cosines. The formulation of visualisation of trigonometric operations can be implemented by teachers in trigonometric learning in schools. In general, the conclusions of this project are: visualisation of trigonometric operations applies to all trigonometric identities constructed from sines and cosines with the greatest degree 2; the sequence of procedures to form a visualisation is multiplication, addition, and subtraction; sine rules and cosine rules can be used to determine the length of the sides of a triangle. |
