No COW this week. As we come to the end of the term, we are working on a series of 8 performance tasks through which students will demonstrate their knowledge, reasoning, and communication skills. I am suspending the COW for the week, so that students can put their full attention towards the tasks. All tasks will be due on Friday at the end of class.
Some review sites that might be helpful with the tasks:

Potential and Kinetic Energy
COW #9 will allow you to practice using algebraic equations with potential and kinetic energy. You will also be trying a new problem solving technique: systematic lists! (This is a link to the problem we did in class today.)

COW POLISHING AND PUBLICATION
COW #8 Reasoning and Communication is due on Friday. It should be typed or neatly handwritten with few to no grammatical/spelling errors. It needs to be correct and have complete and thorough justifications.

Coefficients, Quadratics, and Exponents, Oh My!
COW #8
What does Quadratic mean?
Powers have two parts; a base and an exponent. There are different ways of "saying" powers that you might hear:
* the fifth power of three
* three raised to the fifth power
* three to the power of five, or just
* three to the fifth

What is a term?
Intro to Basic Algebra Terms
What is a coefficient?
A coefficient is a number in front of a variable. For example, in the expressionx2-10x+25 , the coefficient of the x2 is 1 and the coefficient of the x is -10. The third term, 25, is called a constant.
If the expression were -x2+10x+25, the coefficient of the x2 would be -1, and the coefficient of the x would be 10.

What is cross correlation?
cross correlation—The correlation between time series x(t) and y(t), where x and y may represent the same variable measured at different locations, or a single variable measured at one location but at different times, as for the case in which y(t) represents x(t + L), where L is a specified time lag.
In such cases, the two variables are usually not statistically independent, and large cross correlations between x and y can result.
How could this apply to matrix problems?

What is a term?
Terms
A term can be any of the following:
- a constant: e.g. 3, 10, π,
- the product of a number (coefficient) and a variable: e.g. –3x, 11y,
- the product of two or more variables: e.g. x2, xy, 2y2, 7xy
Like terms are terms that differ only in their numerical coefficients. For example: 3a, 22a, are like terms.
