Trigonometry Ratios Table Trigonometry Formula. Students can label the right triangle's sides and angles and define the nine most common rations in trigonometry using both words and symbols. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). Accurate trigonometric ratios for 0°, 30°, 45°, 60° and 90° The trigonometric ratios for the angles 30°, 45° and 60° can be calculated using two special triangles. values of all six trigonometric ratios. 1.
