9th Grade Math: Trigonometric Functions
In mathematics, the trigonometric functions are functions of an angle. They are important in the study of triangles and modeling periodic phenomena, among many other applications. Trigonometric functions are commonly defined as ratios of two sides of a right triangle containing the angle, and can equivalently be defined as the lengths of various line segments from a unit circle.

It will tutor me, hopefully , in trigonometric functions.
I am teaching special ed students algebra and geometry on grade level. I have no materials for bringing them up from 5th grade - 7th grade level to 9th grade -10th grade level.
Tutoring my 9th grade son.
I teach math to 9th grade -12th grade at a small city school in North Carolina. Knowing that each student in NC has to score levels 3 or 4 on the EOC Algebra 1 test to graduate, any real-life application type problems would be beneficial to the success of my students. Knowing also that matrces are heavily tested on the NC EOC test, this website appears that it would be helpful. Our textbooks do not offer many examples of matrices . Thank you.
I am a mathematics teacher and your web site can help me making my assessments and worksheets for the pupils of my class of 8th and 9th grades.
