\n" ); document.write( "\n" ); document.write( "You are a little out of whack here. I think you are trying to define the lower case Greek letter as meaning radians. Not so. is nothing more than a dimensionless transcendental irrational number representing the ratio of a the circumference of a circle to its diameter. I think you are making the association because angle measures expressed in radians frequently are expressed as some multiple of . This is because a complete circle is measured as radians.\r
