Enter any number into the inverse sine calculator. The calculator will display the inverse sine of that number in terms of degrees or radians.
What is the inverse sine?
An inverse sine, also known as an arcsin, is the inverse of the sine function. Typically the sine function takes in angle measurement and a result is a number. The inverse sine performs the opposite operation, so the input is a number and the output is an angle.
What can the inverse sine be used?
The inverse sine can be used when the value of the sine is known, and you want to find the corresponding angle. Often times the value of sine is known because it is also represented as the value of a triangle’s opposite side of the adjacent side of an angle.
If you can then measure those to sides and get the sine value, you can use the inverse sine function to calculate the angle corresponding to that value.
