To prepare for the SAT Mathematics Level I subject test, you can watch our brief, engaging video lessons on trigonometry basics. Though typically less than 10 minutes in length, these videos are quite comprehensive as well as easy to follow. Each lesson also features a short multiple-choice test that allows you to test your trigonometry skills, while also introducing you to the types of questions you're likely to encounter on the SAT Mathematics Level 1 subject test.
SAT Mathematics Level 1 Objectives
If you're a high school student who's successfully completed at least one year of geometry and two years of algebra, achieving a high score on the SAT Mathematics Level I subject test could give you a leg up on your fellow college applicants. This test could prove particularly beneficial if you plan to major in math or a related field, like economics, engineering or science.
The SAT Mathematics Level I subject test is comprised of 50 multiple-choice questions, which you'll have an hour to complete. Approximately 6-8% of the test focuses on trigonometry.
1. List of the Basic Trig Identities
There are specific trig functions that have very special and very simple relationships with each other. Learn the main one and how you can use it to understand the others.
2. Trigonometry: Sine and Cosine
Learn an easy trick to help you solve trigonometry problems, including problems with sine, cosine and inverse trig functions. At the end of this lesson, you'll know what SohCahToa means and how to use it.
3. Trigonometry and the Pythagorean Theorem
Explore how the Pythagorean Theorem can be used in conjunction with trigonometric functions. In this lesson, take an inverse trigonometric function, and define all three sides of a right triangle.
4. How to Solve Trigonometric Equations for X
Adding trigonometric functions into standard algebra equations adds complexity. Learn how to solve trigonometric equations for x and how to use inverse operations to simplify equations.
