All operations are applied to them as if they were finite; but is this permissible ? I think not.* Where is it demonstrated that the differential of an infinite series is found by taking the differential of each term ? Nothing...
Página 2 - J. + cos 3x— &c. an utterly false result, for this series is divergent. " The same remark holds for the multiplication and division of infinite series. I have begun to examine the most important rules which are (at present) esteemed to hold good in this respect, and to shew in what cases they are correct, and in what not so. This work proceeds tolerably well, and interests me infinitely.
Página 4 - Polsson among others has spoken decidedly against their being employed. But that the series which are used, and from which deductions are drawn, ought to be always and necessarily convergent, is a circumstance of which the Author of this Essay has not been at all able to convince himself; on the contrary, it is his opinion that series, as long as they are GENERAL, so that we cannot speak of their convergence or divergence, must always, when properly treated, necessarily and unconditionally produce...

Christiania, 1839) and in which he writes thus: " Divergent series are in general very mischievous affairs, and it is shameful that any one should have founded a demonstration upon them. You can demonstrate any thing you please by employing them, and it is they who have caused so much misfortune, and given birth to so many paradoxes. Can any thing be conceived more horrible than to declare that 0= 1 -2"+ 3" -4

Of the merits of a work of which truth is the object we cannot have an adequate idea nor a perfect relish without some acquaintance with the errors against which it is levelled and which it is...
