Calculate the inverse sine of any number using this calculator. This arcsin calculator converts any number into its arcsin or inverse sine. Select radians or degrees for the units.
Arcsin Formula
The following formula can be used to calculate the arcsin of any number.
Arcsin(x) = C
Sin C = x
This equation essentially says that any arcsin value is equal to the inverse sine value. In more conceptual terms you can think of the arcsin as the angle whose sin is x. The arcsin can be used to calculate the angle when the sine of the angle is given.
