Arcsin Calculator (Inverse Sine Calculator)

Arcsin Calculator

Arcsin calculator finds the angle of a triangle in degrees and radians for the given value. However, the value should be between -1 and 1 to get the arcsin in degrees. It converts the sine into an inverse to find the angle of the triangle.

What is arcsine?

The arcsine of x is defined as the inverse sine function of x when -1≤x≤1. It is the inverse trigonometric function of sine.

When the sine of y is equal to x:

sin y = x

Then the arcsine of x is equal to the inverse sine function of x, which is equal to y:

arcsin x = sin^-1 x = y

How to find arcsin?

To calculate the arcsine for a triangle, follow the below example.

Example:

x = 0.5

Arcsin(x) = ?

Solution:

Step 1: Place the value of x in arcsine function.

Arcsin(0.5)

Step 2: Take the sin^-1 of 0.5 in calculator (scientific).

Arcsin(0.5) = sin^-1(0.5) = 30°

Note: Arcsin of 0 is 0 degree.
