Is This Tool Helpful?

     

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.

Arcsin

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”.

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.
