## Trigonometric Ratios of Special Angles - Free Educational videos for Students in k-12

Transcript
 00:0

#### DESCRIPTION:

This video shows us how we determine the trigonometric ratios for the angles of 30 degrees, 45 degrees, and 60 degrees. Keep in mind that the ratios of the sides corresponding to these angles never change (even though the side lengths may change). That means that knowing the values for these trig ratios means you'll know them forever! They won't change!

#### OVERVIEW:

Trigonometric Ratios of Special Angles is a free educational video by AlRichards314.It helps students in grades HS practice the following standards HSF.TF.A.3.

This page not only allows students and teachers view Trigonometric Ratios of Special Angles but also find engaging Sample Questions, Apps, Pins, Worksheets, Books related to the following topics.

1. HSF.TF.A.3 : Use special triangles to determine geometrically the values of sine, cosine, tangent for π/3, π/4 and π/6, and use the unit circle to express the values of sine, cosine, and tangent for x, π + x, and 2π - x in terms of their values for x, where x is any real number..
