... To clarify this further, if two angles are complementary, such as 40° and 50°, then a trigonometric function of one is equal to the cofunction of the other. That is, sin 40° = cos 50°, sec 40° = csc 50°, and tan 40° = cot 50°. ...

... Area of a triangle There are several ways to calculate a triangle’s area. In hyperbolic and spherical geometry, the area of a triangle is equal to its defect (measured in radians). For the rest of this entry, only Euclidean geometry will be considered. Many formulas for the area of a triangle exist ...
