Arccosine

Determines the angle corresponding to a given cosine. Arccosine is defined in radians from 0 to π. For example, the arccosine of 0.5 is π/6 or 0.5230 radians.

Trigonometric functions are used to model periodic phenomena, such as cyclical seasonal patterns, and wave motion. They form the foundation for advanced analyses in electrical engineering, digital image processing, radiography, thermodynamics, telecommunications, and many other fields in science and technology.

In Minitab, you can use the Calculator to find the arccosine of a number or a column of data.

Arccosine is also called the inverse cosine and can be represented by cos-1 x, arccos x, or acos x.
