If only....

Print Friendly and PDF Years ago I was wishing that my materials (textbooks, workbooks, etc.) allowed me the option of introducing the trig graphs BEFORE doing any right triangle trig. Almost all teaching addresses the special case of right triangle trig before dealing with the whole enchilada. Why?

This sketch would have helped me greatly. The dynamic nature of this sketch enables the teacher and learner many more opportunities than static textbooks.
The file can be found here.
