22 matching sine/cosine graphs (excluding horizontal shift) with 4 extra graphs thrown into the answer bank. Key included. All graphs were computer generated and adjusted to be easy to read for students.

This activity practices finding equations of lines using point-slope or slope-intercept. Includes an answer bank with all potential answers plus a few extra. Includes a key with all potential answers. This is a great differentiated activity to sum up equations of lines while allowing flexibility for students to pick the method (point-slope or slope-intercept) with which they are most comfortable!

Concise notes on coordinates, quadrants, distance formula, midpoint formula, x and y intercepts of equations. Great first section to any Algebra or PreCalculus course. Eight pages of notes contains 9 worked out examples and clear diagrams.

Precalculus Polar Coordinates and Equations Quiz This quiz covers: converting polar to rectangular, converting rectangular to polar (coordinates and equations), graphing. Key included.

Free polar graph paper for graphing polar coordinates or polar equations.

This practices all types of problems that use law of sines and law of cosines. Answers included.

This worksheet teaches how to convert polar equations of lines and circles to rectangular form and graph. There is a review of some identities and completing the square and a few lists of important formulas. Key included.

This worksheet teachers the basics of graphing polar coordinates, using polar graphs. It is step by step and includes a bonus page of blank polar graphs for use in class.

This worksheet uses the sum/difference identities with inverse trig functions. This is a great way to review inverse (sin-1 cos-1 tan-1) trig functions and combine with the sum and difference identities. The first problem is completely worked out and explained with a diagram. Then three additional problems for the students to work out follow. Last page is the answer to the student problems.

A quiz that tests all skills relating to graphs of the six trig functions. A bonus couple of composite problems are at the end. Key included.

This is a great "real life" example using piecewise functions. Students learn the basics of tax brackets and can calculate basic tax owed by using piecewise functions. It is very thorough and includes some practice problems and answers. Highly challenging for an Algebra II or PreCalculus class.

This packet includes 4 assessments: 1 practice assessment with quadrant I filled in 3 Quizzes - fill in the blanks - degrees, radians - fill in the blanks - degrees, radians, coordinates - fill in the blanks - degrees, radians, coordinates, tangent The quality of the images is far superior than everything I had googled before making my own with Geometer's Sketchpad. It is the perfect way to review and teach the unit circle.
