Calculus Made Easy S. P. Thompson

SUMS, DIFFERENCES, PRODUCTS AND QUOTIENTS.

Wk have learned how to differentiate simple algebraical functions such as x2 + c or «j4, and we have now to consider how to tackle the sum of two or more functions.

For instance, let

y = (x2 + c) + (ax4 + b)-,

dy

what will its be? IIow arc we to go to work on this new job? ax

Calculus Made Easy

Silvanus P. Thompson

Calculus Made Easy: Being a Very-Simplest Introduction to Those Beautiful Methods of Reckoning which Are Generally Called by the Terrifying Names of the Differential Calculus and the Integral Calculus is is a book on infinitesimal calculus originally published in 1910 by Silvanus P. Thompson, considered a classic and elegant introduction to the subject.

Some calculus-tricks are quite easy. Some are enormously difficult. The fools who write the textbooks of advanced mathematics and they are mostly clever fools seldom take the trouble to show you how easy the easy calculations are. On the contrary, they seem to desire to impress you with their tremendous cleverness by going about it in the most difficult way. Being myself a remarkably stupid fellow, I have had to unteach myself the difficulties, and now beg to present to my fellow fools the parts that are not hard. Master these thoroughly, and the rest will follow. What one fool can do, another can.
