Web[ i ] sinA in terms of cotA : sinA = 1 / cosecA. We know that: cosec²A = 1 + cot²A. sinA = 1 / √1 + cot²A [ ii ] secA in terms of cotA : We know that: 1 + tan²A = sec²A. secA = 1 + tan²A. secA = 1 + 1 / cot²A. secA = √(cot²A + 1 ) /cotA [ iii ] tanA in terms of cotA : tanA = 1 / cotA WebIn the trigonometric ratios table, we use the values of trigonometric ratios for standard angles 0°, 30°, 45°, 60°, and 90º. It is easy to predict the values of the table and to use the table as a reference to calculate values of trigonometric ratios for various other angles, using the trigonometric ratio formulas for existing patterns within trigonometric ratios …

WebSep 15, 2024 · Example 1.7. Find the values of all six trigonometric functions of \(60^\circ \). Solution: Since we may use any right triangle which has \(60^\circ \) as one of the angles, we will use a simple one: take a triangle whose sides are all \(2 \) units long and divide it in half by drawing the bisector from one vertex to the opposite side, as in the figure on the … WebStrictly speaking, we don't these days. Historically speaking, finding trig values and reciprocals were much much harder than pressing two buttons on a scientific calculator. So people wanted to have separate tables for looking up 1/sin x and so on. In fact, those weren't the only "extra" trig tables people had back then. Check out this fun ... scary math
