Map and Table Calculation

ASIN( ) function

Returns the arc sine, i.e. the inverse sine (sin-1), of a value.

Syntax

ASIN(Value)

Input

Value is a value
Domain type: any Value domain
Value range: [-1,1]

Output

ASIN returns: a real value in radians
Domain: system domain Value
Value range: [-p/2,p/2]

Notes:

Tip:

When the definition symbol = is used, a dependent output map or dependent output column is created; when the assignment symbol := is used, the dependency link is immediately broken after the output map/column has been calculated.

Usable in

MapCalc, TabCalc, Simple calculators

Examples

Pocket line calculator examples:

? ASIN(-0.5)

returns -0.524

MapCalc example:

OutMap1 = ASIN(InMap1)

? 1.571 0.524
0.201 0.305 -1.571
? -0.412 -0.100

 

OutMap2 = RADDEG(ASIN(InMap2))
