Trigonometry Requires Calculus, Not Vice Versa (UMAP)
Author: Yves Nievergelt
After exposing the lack of foundation for trigonometry in the curriculum, this module explains one way to define and compute all the inverse trigonometric functions, inverse hyperbolic functions, and inverse exponenetial functions (logarithms). The theory and algorithms presented here involve only material at the level of first-year calculus. Yet the topics developed might fit in courses from intermediate calculus (after limits, derivatives, and integrals, but possibly in parallel with transcendental functions) to advanced calculus.
