noun
/ˈɑːrk.sɪn/
Definition
The arcsin function, also known as the inverse sine function, is the function that returns the angle whose sine is a given number.
Examples
- To find the angle in a right triangle where the opposite side is 0.5 and the hypotenuse is 1, you would use arcsin(0.5), which equals 30 degrees.
- In programming, you might calculate arcsin in radians using the arcsin function of a math library to determine angles from sine values.
Meaning
Arcsin is the angle whose sine value corresponds to the given input. It’s primarily used in trigonometry and helps find angles based on sine ratios.
Synonyms
- Inverse sine
