ASIN

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

DIFF/1, IC=1.05, FUNCTION=ASIN(DX(21,11)/DM(21,11))
This statement defines a user-specified differential equation. The initial value of the state variable is 1.05. The time derivative of the state variable is the expression:
ASIN(DX(21,11)/DM(21,11))
