Trigonometric formula Encyclopedia card Trigonometric functions are functions of transcendental functions in mathematics that belong to elementary functions. Their essence is the mapping between the set of any Angle and a set of ratios. The usual trigonometric functions are defined in the plane rectangular...

h = a × sin(γ) area = 1 / 2bh Equilateral Triangle Area An equilateral triangle is one where all three sides are equal in length, and all three angles are 60°. Given an equilateral triangle, you can find the area using the length of one of the sides. The formula to find th...
Example 3: Find the area of a triangle-shaped garden given one side of it (say, c) is 15 feet long and the two adjacent angles are 30° and 60°. This task can be resolved using the ASA rule. Solving using the area of a triangle formula c2/ (2 * (tanα-1+ tanβ-1)) = ...
