70 Times 7 Math: Answer Keys to Trigonometry Classwork/Homework

This resource provides the answers to assignments that students complete in 70 Times 7 Math: Trigonometry Classwork/Homework, which is sold separately and supplements the textbook Introduction to Trigonometry, by 70 Times 7 Math. The assignments are meant to provide students individual practice solving problems taught in their textbooks, including problems that relate to sine, cosine, tangent, secant, cosecant, and cotangent trigonometric functions; unit circles; Law of Sines; Law of Cosines; arccosine, arcsine, and arctangent; identities, trigonometric equations, and more. The homework also equips students to do well on the corresponding tests. There are four classwork assignments to help prepare students for each exam. (Computer-based tests and practice tests are available through the Habakkuk Educational Materials website. See pages 5-6 for details. Answer keys to this book can also be purchased from the website.)

Students should complete one of the assignments weekly and then take the test at the end of the fifth week. For homework the 5th week, they can correct any errors from previous assignments or work on a computer-based practice test. It is recommended that students be allowed to correct any errors from a homework assignment before the final grade is calculated, as this tends to help them to do better on the tests. (When using the computer-based tests and practice tests, the grades are calculated automatically.) Each week’s classwork will be in the same format as the test. If there are, let’s say, 80 problems on an upcoming test, students would complete all 80 of those types of problems each week for four weeks, although the answers to corresponding problems will differ from one week to the next.

Questions included on the classwork and tests are not randomly selected from the chapters in focus. Instead, they are very comprehensive in that every type of problem students learn about in their textbook or complete as a class on the interactive whiteboard will also be solved individually by students on the classwork assignments and corresponding tests. Moreover, page numbers where students can turn to for help in their textbooks are specified on the footnotes of each page, and tutorial videos are available in the electronic textbooks. Time should be allotted daily for students to work on these assignments. To contact 70 Times 7 Math, please visit the business website of Habakkuk Educational Materials.
