Once you have successfully completed high school courses in algebra and geometry, you will be ready to study trigonometry. This branch of mathematics focuses on the study of triangles. More specifically, it looks at the relationships between triangle sides and angles, along with the functions of various angles. But there’s a lot more to trigonometry than the Pythagorean Theorem. You will also learn concepts such as sines, cosines, radians, and angle identities, which lay the groundwork for later work in calculus and other advanced math. The concepts introduced in trigonometry are also useful in a number of careers, such architecture, radiology, and navigation.

The trigonometry preparation available with Varsity Tutors’ Learning Tools Learn by Concept provides comprehensive study help. The tool is set up like a class syllabus, with a series of categories that branch off into topics that are more specific. The interactive format allows you to click on any category or topic; doing so brings you to a series of example questions. Each of these questions is presented in multiple-choice format, with a problem and several possible answers. You can look through the answers before working on the problem, and then choose what you think is the correct answer. The actual answer is also provided, allowing you to check and see if you got it correct.

But Learn by Concept does more to be helpful than provide sample questions. Whether you got the answer right or wrong, you can review a detailed explanation of the process used to arrive at the correct answer. Each step, no matter how small, is included in this explanation, allowing you to see every concept that applies. If you got the answer correct, you can confirm that you did the work correctly as well and didn’t just get lucky. If you got the answer wrong, you can find the exact point where you went off track, and figure out what you might need to focus on in order to stay on track in the future.

The Learn by Concept tool can be used as a yearlong trigonometry study guide, as a test review, or even just to nail down one specific topic. All of the broad trigonometry categories are covered, including angles, triangles, trigonometric functions and graphs, and the unit circle. You can also get into the specifics in each category. Thousands of example questions are available. Nearly every possible subject that could come up in your trigonometry class is covered in the Learn by Concept tool.

Although the Learn by Concept tool is useful in its own right, there are a number of other Learning Tools available. You can take a free Full-Length Practice Test to see which areas you already know and which you may need help with. The trigonometry Practice Tests focus on more specific areas, allowing you to spend more time on this material or review your progress. In addition to the Learn by Concept trigonometry example questions, you can work with the free Learning Tools Flashcards for the same topics. Both the Practice Tests and Flashcards can be customized to meet your study needs. Using the Question of the Day tool on a daily basis will help you test your overall trigonometry knowledge with randomized questions from all topics. Using Varsity Tutors’ Learning Tools can help you stay organized and prepared throughout your trigonometry studies.
