DERIVATIVES OF FUNCTIONS OF A SINGLE VARIABLE.When the function . remains continuous between two given limits of the variable ., and that we assign to this variable a value contained between the two limits in question, an infinitely small increment attributed to the variable produces an infinitely small increment of the function itself.

DIFFERENTIALS OF ANY FUNCTION OF SEVERAL VARIABLES EACH OF WHICH IS IN ITS TURN A LINEAR FUNCTION OFLet . be constant quantities, and let .be a linear function of the independent variables . The differential .will itself be a constant quantity, and as a result, the differentials . . . will all be reduced to zero. We immediately conclude from this remark that the successive differentials of the functions
