Algebra 2 Trigonometry topics include circular functions, right triangle ratios, solutions of trigonometric equations, inverses, identities, the laws of sines and cosines, graphs of trigonometric functions, and applications of trigonometric techniques to solve real-world problems. A transformational approach to graphing is used with families of related graphs. Numerical, graphical, and algebraic solutions should be considered for all problems where appropriate. Graphing utilities, especially graphing calculators, are integral to the course. All Virginia Standards of Learning for Trigonometry are included in this course.
Indicators Determine whether a given relation is a function and identify the domain and range.
Perform operations with functions, find composite functions, and find the inverse of a given function, if it exists. Mechanics Benchmark Students apply algebraic techniques to analyze, describe, and compare trigonometric equations and functions. Indicators Change from radian to degree measure and vice versa, find angles that are coterminal with a given angle, and find the reference angle for a given angle. Find the exact and approximate values of the six trigonometric functions of an angle in standard position. Circular functions, the unit circle, and the right triangle will be interrelated.
