History
Main article: History of logarithms 外部ﾘﾝｸ:en.wikipedia.org

The history of logarithms in seventeenth-century Europe is the discovery of a new function that extended the realm of analysis beyond the scope of algebraic methods. The method of logarithms was publicly propounded by John Napier in 1614, in a book titled Mirifici Logarithmorum Canonis Descriptio (Description of the Wonderful Rule of Logarithms).[22][23] Prior to Napier's invention, there had been other techniques of similar scopes, such as the prosthaphaeresis or the use of tables of progressions, extensively developed by Jost Burgi around 1600.[24][25] Napier coined the term for logarithm in Middle Latin, “logarithmus,” derived from the Greek, literally meaning, “ratio-number,” from logos “proportion, ratio, word” + arithmos “number”.

efore Euler developed his modern conception of complex natural logarithms, Roger Cotes had a nearly equivalent result when he showed in 1714 that[30]
log(cos θ +isin θ )=iθ

あらあら、大学数学が無理なんで、高校数学の復習ですか？ｗｗｗ

で、朝鮮高校のヤンキー🐎🦌君に自然対数が定義できるのかな？ｗｗｗ
