This is a worksheet on trigonometry / trig sum and difference formulas. This is a step by step lesson plan on how to find the exact value of trig functions when given an angle not on the unit circle. Students will explore individually or in groups how to find these exact values and how they can be derived. There is also a worksheet with practice problems to shows student comprehension.

This quiz is over trig proofs. Using trigonometric indentities to simplify and verify equations. The trig indentities include: quotient identity, cofunction identity, pythagorean identity, even and odd functions, and reciprical identities. Students will manipulate and substitute trig functions in order to reach the desired result.

This is a beginning lesson of a Spherical Geometry unit in an Advanced Geometry high school class. The students will explore the concepts of geometry on a sphere as opposed to the traditional Euclidean geometry on a plane. The students will need a sphere that they can draw lines and other geometric shapes on throughout these lessons. The students will be exploring the concepts of Spherical Geometry and applying what they already know to discover new concepts. A teacher's guide is included an

Exploring how to find the coordinates of the unit circle using the students' knowledge of the special right triangles and how to use these coordinates to solve for the six trigonometric functions. Included in the lesson is a worksheet for solving for the trig functions, co-terminal angles, complement and supplement angles, converting from radians to degrees, and manipulating the arc length formula.

This 15 question introductory quiz will cover the unit circle as well as concentrate on radians and degrees. The quiz contains angle conversions, coterminal angles, complement and supplement angles, using the arc length formula, and memorizing the unit circle (degrees, radians, and coordinates).
