e++Trigonometry in 3-D Figures 與 HS.Geometry[Lite] 使用情況與統計

Students can create custom situations in the "Custom" mode and use sine formula or cosine formula to find the distances / the bearings between objects. Students can also solve 2-dimensional problems using trigonometry in the "Preset mode". Tools such as angles and dotted lines are provided to aid students in solving the problems. Modern Educational Research Society develops a series of teaching tools and interactive App, to facilitate teachers in implementing scaffolding activities in class, and support students' self-directed learning at home.
