​Trigonometry is a five-unit elective course for high school students who have successfully completed Algebra I, Geometry, and Algebra II. The materials cover a development of trigonometry from right triangle trigonometry to oblique triangles and the polar plane. Throughout the course, students will develop trigonometric formulas and use them in real-world applications, evaluate trigonometric proofs using complex trigonometric identities and solving trigonometric equations with regard to the unit circle
​​NFC Academy works diligently to provide additional materials to our homeschool students which will help bridge the gap from a traditional classroom to the home with a teacher who does not have direct daily live interaction with the student.  These supplementary videos which are typically from Kahn Academy or available through research in YouTube are screened prior to being included.  However, material offered over the Internet, especially using YouTube may change without notice to the user.  We recommend screening of such material by the home to avoid content that may be unacceptable in an advertising promotion which could be added as a part of some videos.
