Understanding Arcsin (Inverse Sine)
Arcsin (sin⁻¹) is the inverse of the sine function. It returns an angle whose sine is the given number. The range of arcsin is:
- -90° to 90° in degrees
- -π/2 to π/2 in radians
For example, if sin(30°) = 0.5, then arcsin(0.5) = 30°.
With this calculator, finding angles becomes simple and fast – just type in a number and get your answer right away! You can also find the length of an arc with our Arc Length Calculator.
Arcsin Table for Common Values
| Sin Value | Arcsin (Degrees) | Arcsin (Radians) |
|---|---|---|
| -1 | -90° | -π/2 |
| -0.5 | -30° | -π/6 |
| 0 | 0° | 0 |
| 0.5 | 30° | π/6 |
| 1 | 90° | π/2 |
FAQs
1. What is the domain of the arcsin function?
The input (sine value) must be between -1 and 1.
2. How do I convert the result from radians to degrees?
Multiply the radian value by 180/π to get degrees.
3. Can I use this calculator for negative values?
Yes, arcsin works for values between -1 and 1, so negative values are valid.
