Trigonometric Ratios of Special Angles
By AlRichards314
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!
