Institutionum calculi integralis – Wikipedia
A general method by which integrals can be found approximately. A large part of Ch. The even powers depend on the quadrature of the unit circle while the odd powers are algebraic. Concerning the integration of rational differential formulas.
Click here for the 8 th Chapter: Examples are provided of course. I have decided to start with the integration, as it shows the uses of calculus, and above all it is very interesting and probably quite unlike any calculus text you will have read already.
Click here for the 5 th Chapter: I have used the word valid in the to indicate such functions, rather than real or actualas against absurd, which Euler uses. Recall that this book was meant as a teaching manual for integration, and this task it performed admirably, though no thought was given to convergence, a charge often laid. Click here for some introductory materialin which Euler defines integration as the inverse process of differentiation. The work is divided as in the first edition and in the Opera Omnia into 3 volumes.
Euler takes the occasion to extend X to infinity in a Taylor expansion at some stages. Euler himself seems to have been impressed with his efforts.
A lot of familiar material is uncovered here, perhaps in an unusual manner: Concerning the resolution of equations in which either differential formula is given by some finite quantity. This chapter is rather labour intensive as regards the number of formulas to be typed out; however, modern computing makes even this task easier. All integraliss all a most enjoyable chapter, and one to be recommended for students of differential equations. At this stage the exclusive use of the constant differential dxwhich can be insttutionum in the earlier work of Euler via Newton is abandoned, so caluli ddx need not be zero, and there are now four variables available in solving second order equations: Other situations to be shown arise in which an asymptotic line is evident as a solution, while some solutions may not be valid.
Concerning the particular integration of differential equations. This is a long chapter, and I have labored over the translation falculi a week; it is not an easy document to translate or read; but I think that it has been well worth the effort.

An integral is established finally for the differential equation, the bounds of which both give zero for the dummy variable, an artifice that enables integration by parts to be carried out without the introduction of extra terms. This chapter completes the work of this section, in which extensive use is made of the above theoretical developments, instiyutionum ends integrais a formula for function of function differentiation.
The use of more complicated integrating factors is considered in depth for various kinds of second order differential equations. This is now available below in its entirety. This chapter relies to some extend on Ch.
It builds on the previous chapter to some extent, and ends with some remarks on double integrals, or the solving of such differential equations essentially by double integrals, a process which was evidently still under development at this time. This lead to an improved method involving successive integration by parts, applied to each of the sections, and leading to a form of the Taylor expansion, where the derivatives of the integrand are evaluated at the upper ends of the intervals.
This task is to be continued in the next chapter. A very neat way is found of introducing integrating factors into the solution of the equations considered, which gradually increase in complexity. The examples are restricted to forms of X above for which the algebraic equation has well-known roots.
Concerning the resolution of other second order differential equation by infinite series.
Concerning the integration of other second order differential equations by putting in place suitable multipliers. This chapter ends the First Section of Book I.
Oh no, there’s been an error
Products of the two kinds are considered, and the integrands are expanded as infinite series in certain ways. Euler’s abilities seemed to know no end, and in these texts well ordered formulas march from page to page according to some grand design. Euler had evidently spent a great deal of time investigating such series solutions of integrals, and again one wonders institytionum his remarkable industry.
