Meaning
The inverse function of the cosine; the angle that has a cosine equal to a given number.
Classification
Nouns denoting relations between people or things or ideas.
Examples
- We can use the arccos function to find the angle in the right triangle where the cosine of the angle is 0.5.
- The calculator returned the arccos of 0.3 as approximately 72.542 degrees.
- To solve the equation, we first take the arccos of both sides of the equation, resulting in an expression with the inverse cosine function.
- The domain of the arccos function is all real numbers from -1 to 1 inclusive, and its range is all real numbers from 0 to pi radians.
- The computer program employed the arccos function to derive the angles at each point and thereby accurately plot the shape.
