Easy Lessons in the Differential Calculus: Indicating From the Outset the Utility of the Processes Called Differentiation and Integration
Excerpt from Easy Lessons in the Differential Calculus
I first took interest in algebra when I found that problems in Single and Double Position could be solved much more readily by algebra than by the rather absurd rules given for such problems in books on arithmetic. In like manner, I could find no interest in the Differential Calculus till, after wading through two hundred pages of matter having no apparent use (and for the most part really useless), I found the calculus available for the ready solution of problems in Maxima and Minima. This little work has been planned with. Direct reference to my own experience at school and college. The usual method of teaching the Differential and Integral Calculus seems to me almost as absurd (quite as absurd it could scarcely be) as the plan by which chil dren, instead of being taught how to speak  whether their own language or another  tare made to learn by rote rules relating to the philosophy of language such as not one grammarian in ten thousand ever thinks about in after life.

About the author
Richard A. Proctor
456 books2 followersRichard Anthony Proctor (23 March 1837 in Chelsea, London – 12 September 1888) was an English astronomer.
He is best remembered for having produced one of the earliest maps of Mars in 1867 from 27 drawings by the English observer William Rutter Dawes.
His map was later superseded by those of Giovanni Schiaparelli and Eugène Antoniadi and his nomenclature was dropped (for instance, his "Kaiser Sea" became Syrtis Major Planum).
He used old drawings of Mars dating back to 1666 to try to determine the sidereal day of Mars. His final estimate, in 1873, was 24h 37m 22.713s, reasonably close to the modern value of 24h 37m 22.663s. Nevertheless, Frederik Kaiser's value of 24h 37m 22.622s is closer.
A crater on Mars is named after Proctor.
