Inverse trigonometric functions are functions that reverse trigonometric functions (in brief). Trigonometric functions are functions of an angle measure. They are primarily used to find lengths of the legs of a triangle (or some triangular relationship). Inverse trigonometric functions are functions of the ratio of lengths of a triangle. They are primarily used to find the corresponding angle of the ratio of the legs of a triangle. There are other uses, but I will keep it brief for this blog.
Every semester, I have to put more effort into explaining inverse trigonometric functions. Although the concept is the same, the students, and their perceptions, change. There are only so many ways I can think of to explain this concept. So I decided to get some help from several online resources. Of course, I suggest that my students do the same, but that’s another blog, for another day.
Here are a few links I came across that should be helpful to students and teachers alike, looking for alternative ways to explain inverse trigonometric functions.
How do you teach inverse trigonometric functions to your students?
