Function ArcSin(x)

# ArcSin

ArcSin(
x             ! (input) numerical expression
)


## Arguments

x

A scalar numerical expression in the range $$[-1,1]$$.

## Return Value

The ArcSin function returns the arcsine of x in the range $$-\pi/2$$ to $$\pi/2$$ radians.

Note

• A run-time error results if x is outside the range $$[-1,1]$$.

• The function ArcSin can be used in constraints of nonlinear mathematical programs.

The functions ArcCos, ArcTan, Sin. Arithmetic functions are discussed in full detail in Arithmetic Functions of the Language Reference.
