Abstract
Using expository text and examples available in 10 college textbooks we identify two conceptions of angles, trigonometric functions, and inverse trigonometric functions that rely on either a static or a dynamic definition of angle. Although the textbooks favor a conception of trigonometric functions that is based on a dynamic conception of angle, they split in their definition of inverse trigonometric functions. We argue that transparency in making explicit how these conceptions can be bridged might be useful in understanding difficulties that emerge when solving problems with inverse trigonometric functions.

Notes
Two-years colleges are post-secondary institutions in the United States that offer the first two years of a college degree. In addition they offer remediation courses in English and mathematics, vocational certificates, and job training. They also offer courses for community enrichment.
Authors use triangle or ratio interchangeably as they describe this approach. We use prefer ratio, but use the author’s preferred terminology when describing the work.
The verification should be that the argument, \( \frac{\sqrt{2}}{2} \) is a number between -1 and 1. The angle that will be obtained will be between –π/2 and π/2.
Students at 2-years institutions can enroll in courses that may transfer to a 4-years degree program in a different institution.
We excluded examples and sections regarding integration and differentiation of these functions because they were not pertinent to this analysis.
Throughout this section we use the letters P, O, R, and Σ to refer to the elements of the quadruplet that define a conception in Balacheff’s model. We keep Σ which is the original notation proposed by Balacheff.
