/2,/2] (that
is, -/2 < ASIN(a) < /2).
The ASIN function computes the arc sine of an expression
a. ASIN is defined only when the absolute value of a is less than or equal
to 1. The range of ASIN is [-/2,/2] (that
is, -/2 < ASIN(a) < /2).
Format
ASIN(a)
Arguments
| a | Any valid function expression. Number of arguments: 1 |
Examples
ASIN(DX(21,11)/DM(21,11))
This function calculates the value of the expression DX(21,11)/DM(21,11) and then applies the ASIN function to the result. The result is in radians.
