Trigonometric Functions

Trigonometric functions (sine, cosine, tangent) map an angle to ratio components on a unit circle. In CalcOS, inputs for trigonometric functions are computed based on active DEG/RAD mode.

Square Root

The square root of a number x is a value y such that y² = x. For example, √16 is 4 because 4 × 4 = 16.
