MTEL Math: Applied Trigonometry - Chapter Summary

Let our expert instructors show you how to take trigonometry concepts and principles and apply them to more complex problems and implement them when solving related word problems. In this chapter we'll cover:

  • Solving oblique triangles with the law of cosines
  • Using the law of cosines to solve real world problems
  • Solving triangles with the law of sines
  • Proving addition and subtraction formulas for tangent, sine and cosine

In this chapter, you can use our engaging video lessons and self-assessment quizzes to solidify your understanding of trigonometric concepts and their applications. With these techniques in mind, you'll be able to face trigonometry problems on your MTEL test with confidence.

MTEL Math: Applied Trigonometry- Chapter Objectives

The Massachusetts Tests for Educator Liscensure (MTEL) Math test is designed to test the preparedness of future educators to teach math in first through 12th grade classrooms. This chapter, Applied Trigonometry, will be most applicable to the Trigonometry, Calculus, and Discrete Mathematics subarea, and will be especially useful for questions dealing with trigonometry. The Trigonometry, Calculus, and Discrete Mathematics subarea accounts for 16% of the exam's score weight and is one of the six testing areas found on the MTEL Mathematics test. The test as a whole consists of 100 multiple-choice questions and 2 open-response assignments and takes 4 hours to complete.
