asin

Block Category: Transcendental

Inputs: Real scalars.

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

Label: Indicates a user-defined block label that appears when View > Block Labels is activated.

 

Examples

1. Computation of sin-1(1) = π/2; sin-1(0) = 0

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.
