Inverse Sine Calculator or Sin Inverse Calculator or sine inverse calculator: Looking for an easy tool to calculate the inverse of sine? Our arcsin calculator is the best free online tool that gives you accurate answers in a short span of time. You can also learn more about this concept easily and quickly with this tool. We have given detailed steps to do it manually.

How to Find Arcsin(Inverse of sine)?

Arcsin is the trigonometric function that gives the value of inverse sine. It can be represented as sin-1(x). Simply, it helps to find the angle of the triangle with the known value of sine.

Let us look into the trigonometric formula of Arcsin,

y = sin(x) | x = arcsin(y)

Here,

arcsin(y) = sin-1(y).

y = angle(a).

Now let us look into the graph of the inverse sine.

Arcsin Graph:

The inverse sine graph forms a curve from (-1, -π/2) to (1, π/2).

Arcsin Table:

The below table shows you the values of sine and inverse sine along with degrees and radians.

     x arcsin(x) in degrees arcsin(x) in degrees
-1 -90° -π/2
-√3/2 -60° -π/3
-√2/2 -45° -π/4
-1/2 -30° -π/6
0 0° 0
1/2 30° π/6
√2/2 45° π/4
√3/2 60° π/3
1 90° π/2

Steps to Calculate Inverse of Sine

We are providing you with the step-by-step process that calculates the arcsin of an angle.

  • Let us note down the value to find as it is already given in the problem.
  • After that, apply the formula and take the value from the table.
  • Then, after simplification, you will get the value of inverse sine.

Example:

Question: Find the value of Arcsin(1) in radians?

Solution:

Given, Arcsin(1) =?

we know that,

sin(90°) = 1 from the above table.

Apply the formula,

y = sin(x) | x = arcsin(y)

sin(90°) = 1 => 90° = sin -1 (1)

Therefore, Arcsin(1) = 90° = π/2 (in radians).
