This calculator helps you find the angle for a given trigonometric value using the inverse functions: Arcsin, Arccos, and Arctan. The result is provided in both degrees and radians.
Inverse trigonometric functions determine the angle when you know the ratio of the sides of a right triangle. The functions available are:
- Arcsin(x): Calculates the angle whose sine is x. The input value x must be between -1 and 1.
- Arccos(x): Calculates the angle whose cosine is x. The input value x must be between -1 and 1.
- Arctan(x): Calculates the angle whose tangent is x. The input value x can be any real number.
The fundamental relationship for Arcsin is:
Angle = arcsin(x)
Example:
Let's find the angle whose sine is 0.5.
- Select the Arcsin function.
- Enter the value 0.5.
- The calculator will show the result: 30° (which is approximately 0.524 radians).
