This is the last chapter in this section.

The technique is to produce a complete or exact differential, and this is shown in several ways. This is a most interesting chapter, in which Euler cheats a little and writes down a biquadratic equation, from which he derives a general differential equation for such transcendental functions.

Particular simple cases involving inverse trigonometric functions and logarithms are presented first. Commentationes arithmeticae 3rd part Leonhard Euler. This is clearly a continuation of the previous caluli, where the method is applied to solving y for some function of Xusing the exponential function with its associated algebraic equation.

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 integralix of Cauchy on complex integration is required to solve this difficulty.

A general method of analyzing integrating factors in terms of consecutive powers equated to zero is presented.

Oh no, there’s been an error

There is much material and food for thought in this Chapter. This is the most beautiful of chapters in this book to date, and one which must have given Euler a great deal of joy ; there is only one thing I suggest you do, and that is to read it.

This chapter ends the First Section of Book I. It seems best to quote the lad himself at this point, as he put it far better than I, in the following Scholium:. A very neat way is found of introducing integrating factors into the solution of the equations considered, which gradually increase in complexity.

I hope that people will come with me on this great journey: Click here for the 10 th chapter: Concerning the development of integrals as infinite products. Click here for the 9 th chapter: Euler takes the occasion to extend X to infinity in a Taylor expansion at some stages.

Concerning second order differential equations in which one of the variables is absent. Those who delight in such things can see the exponential function set out as we know it, and various integrations performed, including the derivation of some very cute series, as Euler himself notes in so many words.

Here Euler lapses in his discussion of convergence of infinite series; part of the trouble seems to be the lack of an analytic method institutiohes approaching a limit, with which he has no difficulty in the geometric situations we have looked at previously, as in his Mechanica.

Initially a solution is established from a simple relation, and then it is shown that on integrating by parts another solution also is present.
