About this document
Trigonometric Ratios of Special Angles by samm is a document available to read on EtoBox.
This document discusses the trigonometric ratios of special angles 0°, 30°, 45°, 60° and 90°. It explains that these angles always lie in the first quadrant and can be determined using properties of equilateral triangles and right triangles. The trigonometric ratios of 30° and 60° are found using an equilateral triangle. The ratios of 45° are determined from an isosceles right triangle. The ratios of 0° and 90° are based on the coordinates of points on a unit circle. A table of ratios for these special angl
