Finding the angle of a trigonometric function given its decimal value is a crucial skill in various fields, including mathematics, engineering, and computer programming. It allows us to determine the angle associated with a specific trigonometric ratio, such as sine, cosine, or tangent.
The inverse trigonometric functions, also known as arcus functions, are used to find the angle given the decimal value of a trigonometric ratio. The most common inverse trigonometric functions are:
