• 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.

Example

CLEAR
? SIN(0)  && Displays 0.00
? SIN(PI( )/2)  && Displays 1.00
