              Linear thinkers concluded that by taking the world
              apart, the actions of people were more predictable
              and controllable.                     --David Morris
                                                    (Conference
                                                    presentation,
                                                    Fairfield
                                                    University,

     Linear differential equation (Math.), an equation which is
        of the first degree, when the expression which is equated
        to zero is regarded as a function of the dependent
        variable and its differential coefficients.
  
     Linear equation (Math.), an equation of the first degree
        between two variables; -- so called because every such
        equation may be considered as representing a right line.
        
  
     Linear measure, the measurement of length.
  
     Linear numbers (Math.), such numbers as have relation to
        length only: such is a number which represents one side of
        a plane figure. If the plane figure is square, the linear
        figure is called a root.
  
     Linear problem (Geom.), a problem which may be solved
        geometrically by the use of right lines alone.
  
     Linear transformation (Alg.), a change of variables where
        each variable is replaced by a function of the first
        degree in the new variable.
        [1913 Webster]
