**Block Category:** Transcendental

**Inputs:** Real scalars.

**Description:** The asin block produces the inverse
sine of the input signal. The output is an angle in radians.

**Label:** Indicates a user-defined block label that appears when

**1. Computation of sin ^{-1}(1) = **

This equation is realized as:

Two const blocks, set to 0 and 1, are fed to the asin blocks. For comparison, the constant value of π/2 is generated by feeding two const blocks, set to 22 and 14, into the / block. From the results obtained, the asin blocks yield correct values for the angles.
