Much light is shed on the methods promulgated in the previous chapter, and this chapter should be read in conjunction with the preceding two chapters. Several examples are treated, and eventually it is shown that any given integration is one of four possible insyitutionum, all of which must be equivalent. Click here for the 4 th chapter: Initially a solution is established from a simple relation, and then it is shown that on integrating by parts another solution also is present. Following which a more general form of differential expression is integrated, applicable to numerous cases, which gives rise to an iterative expression for the coefficients of successive powers of the independent variable.

E Click here for some introductory materialin which Euler defines integration as the inverse process of differentiation.

The examples are restricted to forms of X above for which the algebraic equation has well-known roots. Eventually he devises a shorthand way of writing such infinite products or their integrals, and investigates their properties on this basis. Now here the use of this method, which we have arrived at by working backwards from a finite equation to a differential equation, is clearly evident.

This is a harder chapter to master, and more has been written by way of notes by me, though some parts have been left for you to discover for yourself.

Click here for the 5 th chapter: This chapter is also rather labour intensive as regards the number of formulas to be typed out; here a more general second order differential equation is set up and integrated by a series expansion.


This is set equal to a chosen function Uwhich is itself differentiated w.

Serious difficulties arise when the algebraic equation has multiple roots, and the method of partial integration is used; however, Euler tries to get round this difficulty with an arithmetical theorem, which is not successful, but at least provides a foundation for the case of unequal roots, and the subsequent work of Cauchy on complex integration is required to solve this difficulty.

Concerning the integration by factors of second order differential equations in which the other variable y has a single dimension. It seems best to quote the lad himself at this point, as he put it far better than I, in the following Scholium: A simple theory of functions is used to show how this comes about; later Euler establishes the conditions necessary for a particular relation to give rise to the required first order d.

Click here for the 3 rd Chapter: Whereby we shall set out this argument more carefully. This is the end of Euler’s original Book One. Click here for the 9 th chapter: This chapter follows on from the previous one: Click here for the 7 th Chapter: In this chapter there is a move into functions of two variables. This is now available below in its entirety. There are of course, things that Euler got wrong, such as the convergence or not of infinite series; these are put in place as Euler left them, perhaps with a note of the difficulty.

Thus, the differential equation becomes equal to a function U with the limits w.

Click here for the 8 th Chapter: This marks the end of Section I. Concerning the resolution of other second order differential equation of the form. Click here for the 1 st Chapter: Concerning homogeneous second order differential equations, and those which can be reduced to that form. This leads to the listing of numerous integrals, on continuing the partial integrations until simple integrals are arrived at; the cqlculi culminates with the sine and cosine function being linked to an exponential function integraalis the angle ; the case where such an exponent disappears on summing to infinite is considered.


Concerning the integration of differential equations by the aid of multipliers. Progressively more difficult differentials are tackled, which often insritutionum be integrated by an infinite series expansion. This is a long but interesting chapter similar to the two above, but applied to more complex differential equations; at first an equation resembling that of a vibrating string is investigated, and the general solution found.

Concerning the integration of rational differential formulas. He then shows how this criterion can be applied to several differential equations to show that they are in fact integrable, other than by using an integrating factor ; this includes a treatment of the normal distribution function. I have institutionnum away with instituionum sections and parts of sections as an irrelevance, and just call these as shown below, which keeps my computer much happier when listing files.
