HELLO, students and parents!

 

This is the 26th week of school and the 1st week of the 4th, and FINAL,  9-weeks grading period. 

 

A reminder that if any student is absent, they are expected to watch the video of that day’s lecture, found either on the YouTube link on their math page or in the shared google folder, so that they are up to speed when they return.  Also, I am in my classroom each morning at 8:00 AM for tutorials (Wednesday duty, though, at 8:20 AM.)

New Homework/Worksheet policy goes into effect starting this Monday, March 18, 2019:

Hard copies of all worksheets from sections covered in between exams are due the day of the exam over those sections at the beginning of class.  These WS packets will count as two daily grades, so with 3 exams per grading period, the WS practice packets will count as 6 total grades.  Work will be graded as a completion grade, but I reserve the right to count any problem for accuracy if I believe it was just copied from the online key without original thought and attempts at understanding.

100%-all problems earnestly attempted (not just copied)

75%-if any single problem is not earnestly attempted, up to 75% left not

earnestly attempted, not just blank.

50%-half not done or earnestly attempted

25%-only a quarter earnestly attempted

0%-WS copied from key (none earnestly attempted) or not turned in.

MATH BIO:

Guillaume-François-Antoine Marquis de L'Hôpital, Marquis de Sainte-Mesme, Comte d'Entremont and Seigneur d'Ouques-la-Chaise (a name almost as big as his hair!) (1661 – 1704) was a French mathematician.  His name is widely known for the theorem/rule used to calculate the limiting value of a fraction whose numerator and denominator either both approach zero or both approach infinity,

 

L'Hôpital is commonly spelled as both "L'Hospital" and "L'Hôpital."  The Marquis spelled his name with an 's'; however, the French language has since dropped the 's' (it was silent anyway) and added a circumflex to the preceding vowel.

 

L'Hôpital was born in Paris, France. His father's name was Anne-Alexandre de L'Hôpital (Lieutenant-General of the King's army). His mother's name was Elisabeth Gobelin (daughter of Claude Gobelin, Intendent in the King's Army and Councilor of the state).  He initially had planned a military career, but poor eyesight caused him to switch to mathematics.  He solved the brachistochrone problem, independently of other contemporary mathematicians, such as Isaac Newton.  He died in Paris.

MATH FACT:

L'Hôpital is the author of the first textbook on infinitesimal calculus, entitle l'Analyse des Infiniment Petits pour l'Intelligence des Lignes Courbes.  Published in 1696, the text includes the lectures of his teacher, the Swiss mathematician Johann Bernoulli (who learned calculus straight from his best friend, the discoverer of infinitesimal calculus, Leibniz.  By the way, Johann also taught the great Leonhard Euler!!), in which Bernoulli discusses the indeterminate form 0/0.  It is the method for solving such indeterminate forms through repeated differentiation that bears his name.

 

In 1694 he forged a deal with Johann Bernoulli.  The deal was that L'Hôpital would paid Bernoulli 300 Francs a year for the rights to publish all Bernoulli’s original mathematical discoveries, which L’Hôpital would then describe in his book.  In 1704, after L'Hôpital's death, Bernoulli revealed the deal to the world, claiming that many of the results in L'Hôpital's book were due to him.  Many refuted Bernoulli’s claims, but in 1922, texts were found that give support for Bernoulli.  The widespread story that L'Hôpital tried to get credit for inventing de L'Hôpital's rule is false: he published his book anonymously, acknowledged Bernoulli's help in the introduction, and never claimed to be responsible for the rule. 

 

As is often the case, the credit goes to he who publishes first.

 

MATH QUOTE

“I must own myself very much obliged to the labours of Messieurs Bernoulli (Johann and his brother Jakob), but particularly to those of the present Professor at Groningen (Johann).  I have made free use of their discoveries, as well as those of Mr. Leibniz, so that I frankly return to them whatever they please to claim as their own.”— L'Hôpital

 

LIMERICK:

With limits, one can feel like a fool,

But there’s a fun, easy way that is cool.

The founder was truly

One Johann Bernoulli,

But, surprise, it’s called L’Hôpital’s Rule!

 

Have a great week,

Mathematics is not a careful march down a well-cleared highway, but a journey into a strange wilderness, where the explorers often get lost. Rigour should be a signal to the historian that the maps have been made, and the real explorers have gone elsewhere.--W.S. Anglin
