Parameters

nExpression

Specifies an angle whose sine SIN( ) returns. nExpression can assume any value and the value returned by SIN( ) ranges between –1 and 1.

Note
nExpression is specified in radians. Use DTOR( ) to convert an angle from degrees to radians. The number of decimal places displayed by SIN( ) can be specified with SET DECIMALS.

Return Value

Example

	Copy Code
CLEAR ? SIN(0) && Displays 0.00 ? SIN(PI( )/2) && Displays 1.00 ? SIN(DTOR(90)) && Displays 1.00
