All corrections for all quadratics work (up to and including Squares and Expansions) are due Thursday, May 17 before 3:30pm. Any corrections received after this deadline will be subject to a late penalty. Any work that is submitted for this deadline that is not 100% correct cannot receive full credit (credit will depend on the amount of correct work).

# Mar 15: Revisions for Measuring Your World DP Update, Part 1

If you received a B or lower on your Measuring Your World DP Update, Part 1, you are expected to check in with me to determine the revisions you would need to do to get an additional grade point.

# Feb 27: SAT Prep Classes

HTHNC is offering after school SAT Prep Classes for Juniors and Sophomores starting Monday March 5 in preparation for the May 5 and June 2 SAT. The class will be from 3:45-5:45 with an hour of Math and an hour of Writing. Classes will meet weekly for seven weeks until May 3.

# Feb 20: POW #2 Due Date Change

The due date for POW #2 has changed from Friday, February 23 to Tuesday, February 27 (at the beginning of class).

The late deadline has not changed: it remains Friday, March 2 (at the beginning of class).

For the "Measuring Your World" project, you will be doing another DP update. A big part of this update will be explaining how you learned about 8 trigonometric formulas:

1. Sine
2. Cosine
3. Tangent
4. ArcSine
5. ArcCosine
6. ArcTangent
7. Law of Sines
8. Law of Cosines

You will basically write a narrative that summarizes the major steps in your learning. Those steps are:

1. Proving the Pythagorean Theorem
2. Using the Pythagorean Theorem to derive the Distance Formula
3. Using the Distance Formula to derive the equation of a circle centered at the origin of a Cartesian coordinate plane
4. Defining the Unit Circle
5. Finding points on the unit circle (at 30 degrees, 45 degrees and 60 degrees)
6. Using the symmetry of a circle to find the remaining points on the unit circle
7. Using the unit circle to define sine and cosine (of the angle theta)
8. Defining the tangent function
9. Using similarity and proportions to derive the general trigonometric functions (sine, cosine and tangent)
10. Using the unit circle to define the arcSine, arcCosine and arcTangent functions
11. Using the Mount Everest problem to discover the Law of Sines ("taking apart")
12. Deriving the Law of Sines
13. Deriving the Law of Cosines

In your narrative, you should emphasize the importance (that is, the application) of each of the 8 functions: in other words, you must explain when they are used to solve problems related to the most basic of 2-dimensional shapes: the triangle.

This "announcement" will soon become an "assignment"; that is, this part of your DP will be graded separately from the rest of the project work that will be posted to your DP.
