HELLO, students and parents!

 

This is the 31st week of school and the 6th 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 went into effect 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.

Seniors - green cord hours are due - May 1st!

Green Cord service hours are due in Career Cruising for Seniors by May 1st in order to be considered for this recognition at graduation. Seniors must have accumulated at least 150 service hours since the summer of his/her freshman year. Thank you to all students who find time to give back to the community!

MATH BIO:

Joseph-Louis Lagrange (1736 – 1813), born Giuseppe Lodovico (Luigi) Lagrangia, was an Italian-born mathematician and astronomer, who lived part of his life in Prussia and part in France, making significant contributions to all fields of analysis, to number theory, and to classical and celestial mechanics. On the recommendation of Euler and D'Alembert, in 1766 Lagrange succeeded Euler as the director of mathematics at the Prussian Academy of Sciences in Berlin, where he stayed for over twenty years, producing a large body of work and winning several prizes of the French Academy of Sciences. Lagrange's treatise on analytical mechanics, Mécanique Analytique, written in Berlin and first published in 1788, offered the most comprehensive treatment of classical mechanics since Newton and formed a basis for the development of mathematical physics in the nineteenth century.

 

MATH FACT:

The Euler-Lagrange equation or Lagrange's equation, developed by Leonhard Euler and Joseph-Louis Lagrange in the 1750s, is the major formula of the calculus of variations. It provides a way to solve for functions which optimize a given cost functional. It is widely used to solve optimization problems, and in conjunction with the action principle to calculate trajectories. It is analogous to the result from calculus that when a smooth function attains its extreme values its derivative goes to zero.

 

 

MATH QUOTE

“As long as algebra and geometry have been separated, their progress have been slow and their uses limited; but when these two sciences have been united, they have lent each mutual forces, and have marched together towards perfection.”—Joseph Lagrange

 

“Just let me know if you wanna go to that home out on the range.”—La Grange, ZZ Top

 

LIMERICK:

The Euler-Lagrange equations in verse:

 

When jumping from high in a tree,
Just write down del L by del z.
Take del L by z dot,
Then t-dot what you've got,
And equate the results (but quickly!)

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
