Cuprien earned a national reputation for his paintings of the iridescent effects of sunlight and moonlight on calm seas. He was a founding member of the Laguna Beach Art Association, serving as president from 1921 to 1922. He bequeathed his entire estate to the LBAA, and the works of art, including these examples, are now part of the museum’s permanent collection.

Preface
The present volume is a sequel to my earlier book, Calculus Deconstructed: A Second Course in First-Year Calculus, published by the Mathematical Association in 2009. I have used versions of this pair of books for severel years in the Honors Calculus course at Tufts, a two-semester “boot camp” intended for mathematically inclined freshmen who have been exposed to calculus in high school. The ﬁrst semester of this course, using the earlier book, covers single-variable calculus, while the second semester, using the present text, covers multivariate calculus. However, the present book is designed to be able to stand alone as a text in multivariate calculus. The treatment here continues the basic stance of its predecessor, combining hands-on drill in techniques of calculation with rigorous mathematical arguments. However, there are some diﬀerences in emphasis. On one hand, the present text assumes a higher level of mathematical sophistication on the part of the reader: there is no explicit guidance in the rhetorical practices of mathematicians, and the theorem-proof format is followed a little more brusquely than before. On the other hand, the material being developed here is unfamiliar territory, for the intended audience, to a far...

...Acceleration Worksheet. Name: _________________________
Date: ______________
14.2 Acceleration
Acceleration is the rate of change in the speed of an object. To determine the rate of acceleration, you use the formula below. The units for acceleration are meters per second per second or m/s2.
A positive value for acceleration shows speeding up, and negative value for acceleration shows slowing down. Slowing down is also called deceleration.
The acceleration formula can be rearranged to solve for other variables such as final speed (v2) and time (t).
EXAMPLES
1. A skater increases her velocity from 2.0 m/s to 10.0 m/s in 3.0 seconds. What is the skater’s acceleration?
Looking for
Acceleration of the skater Solution
The acceleration of the skater is 2.7 meters per second per second.
Given
Beginning speed = 2.0 m/s
Final speed = 10.0 m/s
Change in time = 3 seconds
Relationship
2. A car accelerates at a rate of 3.0 m/s2. If its original speed is 8.0 m/s, how many seconds will it take the car to reach a final speed of 25.0 m/s?
Looking for
The time to reach the final speed. Solution
`
The time for the car to reach its final speed is 5.7 seconds.
Given
Beginning speed = 8.0 m/s; Final speed = 25.0 m/s
Acceleration = 3.0 m/s2
Relationship
1. While traveling along a highway a driver slows from 24 m/s to 15 m/s in 12 seconds. What is the automobile’s acceleration? (Remember that a negative value indicates a slowing down...

Cell Energy Worksheet
Answer the following questions:
Cellular respiration:
• What is cellular respiration and what are its three stages?
A living version of internal combustion-is the main way that chemical energy is harvested from food and converted to ATP energy, it is also called an aerobic process, which is just another way of saying that it requires oxygen. So cellular respiration is defined as the aerobic harvesting of chemical energy from organic fuel molecules. The three stages are; glycolysis, the citric acid cycle, and the electron transport.
• What is the role of glycolysis? Include the reactants and the products. Where does it occur?
The word itself means “splitting sugar”. That is what happens during glycolysis, a six-carbon glucose molecule is broken in half, forming two three-carbon molecules it requires two ATP molecules per glucose. The three-carbon molecules then donate high-energy electrons to NAD+ the electron carrier, forming NADH. In addition to NADH, glycolysis also makes four ATP molecules directly when enzymes transfer phosphate.
• What is the role of the citric acid cycle? Include the reactants and the products. Where does it occur?
This cycle also called the “Krebs cycle”, completes the breakdown of glucose all the way to CO2, one of the waste products off cellular respiration. The enzymes for the citric acid cycle are dissolved in the fluid...

...online (found by using the Library Databases) or in print. These articles are written by experts in a field of study and tend to longer, more in-depth then articles you find in newspapers and magazines. Scholarly articles are also supported by references to other research on the subject that it is discussing. Before being published a scholarly article is brought before a panel of experts (hence peer-reviewed) to be critiqued and assure that the quality of the research is sound.
Scholarly articles can come in all shapes and sizes depending on the subject being covered and the type of research being performed. For example, a scholarly article by an expert in the Humanities will write what is called a literature review, wherein they discuss a work of art (book, painting, etc …) and their research will be based off of what previous experts have written about that piece. However, a scholarly article by an expert in a Science field may write about an experiment they have performed, and discuss their results and how it relates to previous research.
Despite the fact that the content and format of these articles can vary from article to article, if you continue reading, I will list five sure-fire ways to tell if the resource you are looking at is scholarly or not To determine whether what you've found is a credible or reliable source, the first thing to do is read it all..
How do these articles reflect bias on the authors’ part? If so, what is the bias? If...
