"It is clear that the chief
end of mathematical study must be to make the students
think."—John Wesley

HELLO, students and parents!
This is the 31^{st} week of
school and the 6^{th} week of the 4^{th},
and FINAL, 9weeks 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!
Prom tickets will be sold
the week of April 15th and April 22nd during all
lunches. Students must have their student ID to purchase
tickets. Tickets have be purchased before the end of
lunches on April 26th. There will be no tickets sold at
the door. Juniors or Seniors who bring a guest who is
not an NBHS student must pick up the guest permission
slip in the back office and returned it filled out when
they purchase tickets.

MATH BIO:
JosephLouis
Lagrange (1736 – 1813), born Giuseppe Lodovico (Luigi)
Lagrangia, was an Italianborn 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
EulerLagrange equation or Lagrange's equation,
developed by Leonhard Euler and JosephLouis 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 EulerLagrange 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 tdot what you've got,
And equate the results (but quickly!)
Have a great
week,
Kevin W.
