Table of Contents:
Insert a decimal value between 1 and -1 in the Arcsin calculator to find the inverse of sine.
The inverse sine calculator finds the inverse of the sine value in different units and provides a step-by-step guide. This value further helps to find the unknown angle of a triangle.
This calculator gives the value of Arcsin in the following units:
- Radians
- Degrees
- Arcminutes and seconds
What is Arcsin?
The arcsin is the opposite or inverse of a trigonometric function “sine”, given that the value of sine (x) lies between 1 to -1.
For the arcsin to be equal to the inverse of sine (arcsin x =sin-1x), the value of sine y should be equal to x. I.e. Sin y = x.
Arcsin is written as “sin-1” or “asin”.
Arcsin Table:
| X | Arcsin in degrees |
| -1 | -90 |
| -√3/3 | -60 |
| -√2/2 | -45 |
| -1/2 | -30 |
| 0 | 0 |
| 1/2 | 30 |
| √2/2 | 45 |
| √3/3 | 60 |
| 1 | 90 |
How to find Arcsin?
To calculate arcsine, follow the example given below.
Example:
What is the inverse of sine function if X = 0.65?
Solution:
Step 1: Place the value of x in the inverse of the sine function.
= Arcsin (0.65)
Step 2: use a scientific calculator to find sin-1(0.65).
= sin-1(0.65) = 40.5°
