Numeric

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.
