The Trigonometric ratios table helps you to find the values of trigonometric standard angles 0°, 30°, 45°, 60° and 90°. The values of the angle are important for solving various trignometry problems. In mathematics, the trignometric functions relates the angles of a triangle to the len...
If the angle is unknown, but the lengths of the adjacent side and the hypotenuse of a right angle triangle are given, then calculating the cosine can be done by dividing the adjacent side by the hypotenuse (side c as per the figure above). For example, if one needs to find cot(α) ...

The Reuleaux triangle has the smallest possible area for its width and the circle the largest. There also exist non-circular smooth and even algebraic curves of constant width. Definite integrals that describe circumference, area, or volume of shapes generated by circles typically have values that ...
