Linear differential (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.
