Cornelia Fuller Survey of Mathematical Methods Liar Liar Tonya Meisner September 16th‚ 2012 This week’s assignment is about the use of misleading statistics. Companies and individuals use statistics in a variety of way in order to provide information on certain things. The use of misleading statistics‚ while not ethical‚ could be viewed as valuable‚ if it increases profit margins or awareness of the stated topic of the statistic in a biased way. Question number 8 provides a statistic that

Physics Lab Report#3 “Determining the period of a pendulum” Name: Fei Huo Date performed: October 1st‚ 2014 Period 5 Teacher: Mr. Glasel Purpose: The Purpose of this Lab was so that my classmates and I can examine what kind of factors affect the period of a pendulum. Introduction: In a simple form‚ the pendulum is a weight hung from a long string that Galileo discovered that it can be used to track the passage of time very accurately around 400 years ago. In this

Look Think Motion can be described using graphs. Graphs and charts are common tools used in science. To interpret graphs‚ read the axis labels as well as the numbers on the axis. The title should give you some clue as to the purpose of the graph. Next‚ examine the content. Try to describe the content in words‚ using “As ____(quantity on the x axis)‚ ____(type of change‚ such as increases or decreases)‚ ____ (quantity on the y axis) ___(type of change such as increases

Example 1: Does the curve y = 2x3 – 2 crosses the x-axis between x = 0 and x = 2? Solution: Solving for the given values of x‚ at x = 0‚ then y = 2(0)3 – 2 = -2‚ the curve is below the x-axis at x = 2‚ y = 2(2)3 – 2 = 16 – 2 = 14‚ the curve is above the x-axis‚ So the curve crosses the x-axis between x = 0 and x = 2 since y = 2x3 – 2 has a solution found between this interval. Example 2: From the curve y = x5 - 2x3 – 2‚ is there a solution between x = 1 and x = 2? Solution: Using the given

J. Wijayakulasooriya ABSTRACT 2D vector plotters are designed to take a pointer to any given coordinate in the xy plane. An application of this plotting device is in PCB drilling. In PCB drilling the location of the drill holes are fed into the system which will drill the PCB at the specified coordinates. The main objective of this project is to be able to take a pointer to these set of coordinates along the shortest path. The parameter measured is the length of the path taken. Path planning and

fePolar coordinates are two-dimensional and thus they can be used only where point positions lie on a single two-dimensional plane. They are most appropriate in any context where the phenomenon being considered is inherently tied to direction and length from a center point. For instance‚ the examples above show how elementary polar equations suffice to define curves—such as the Archimedean spiral—whose equation in the Cartesian coordinate system would be much more intricate. Moreover‚ many physical
