Students will be able to use the addition and subtraction, half-angle, and double-angle formulas to find the values of trigonometric functions at angles that are not necessarily multiples of 30, 45, 60, or 90 degrees. Content None Specified Limits Stimulus Items may be set in real world or mathematical context. Attributes Angle measures may be in degrees or radians. Items should be assessed without the use of technology. Response Answers must be in exact radical form rather than decimal form. Attributes Answers do not necessarily have to be in simplest radical form. What is the exact value of cos · cos + sin· sin ? Sample Items Correct Answer: What is the exact value of cos 75˚? Correct Answer: B Reporting Geometry Category Standard Expressing Geometric Properties with Equations MAFS.912.G-GPE.1.1 Benchmark Number Benchmark Derive the equation of a circle of given center and radius using the Pythagorean Theorem; complete the square to find the center and radius of a circle given by an equation.
