Algebra II / Trigonometry (TRI)
Algebra II / Trigonometry is another of Acces' core instructional modules. It provides teachers with 16,000 free-response problems covering advanced algebra, trigonometry, and some pre-calculus topics. The module is very thorough in its coverage, provides lots of challenging problems, and is a good supplement to most advanced algebra textbooks.
The following list provides an overview of the module's 161 categories (topics):
- Algebra review
- Radical expressions, rational exponents
- Complex numbers
- Quadratic equations and inequalities
- Linear equations in two variables
- Linear systems
- Theory of roots
- Introduction to functions
- Polynomial and rational functions
- Exponential and logarithmic functions
- Sequences and series
- Right triangle trigonometry
- Arcs, angles, and the wrapping function
- Circular trigonometry
- Trigonometric functions and graphs
- Trigonometric identities and equations
As one of EducAide's core modules, Algebra II / Trigonometry is useful for both instruction and Assessment. Though designed for math classes in grades 11–12, it would be quite appropriate for an introductory algebra course at the college level. Much of the database that covers functions, systems of equations, and right triangle trigonometry could also be used in grades 9–10, and the more advanced topics would be suitable for review in a calculus course.
The principal author of the Algebra II / Trigonometry module is Janet Fortney, a high school and community college math teacher, currently at Charlotte Country Day School (NC).
