Arcsin Calculator – Online Inverse sine Calculator
Defination: Arcsin is define as the inverse of x = sin(y) function.
Formula: arcsin(x) = sin-1(x) = y + 2kπ
For every k = {…,-2,-1,0,1,2,…}
Now, we will take an example to understand the formula.
Example: Find the Arcsin of 0.4
arcsin(0.4) = sin-1(0.4) = y + 2kπ
= 23.57817848 degrees or 0.41151685 radians
Calculation:
arcsin 0.4 = sin⁻¹ 0.4 = 23° 34′ 41.443″
= 23.57817848° + k×360° (k=..-1,0,1,..)
= -336.42182152°, 23.57817848°, 383.57817848°, ..
= 0.41151685rad + k×2π (k=..-1,0,1,..)
= -1.86901012π, 0.13098988π, 2.13098988π, ..
