EGR 140 Scientific Programming Assignment # 7 Spring 2017 Use MATLAB to solve each problem by writing script files; copy and paste the script file AND the results in the Command Window and/or plot in the Figure Window to a WORD document that has your name and section in the headers of each page and the page number in each footer. Edit the output to remove extra lines and empty spaces. The script files SHOULD have comments for easy readability; take a print out of the Word file and staple before submission. Due by 3 PM on April 11, 2017. Write a used-defined function that calculates the average and the standard deviation of a list of numbers. Use the function to calculate the average and the standard deviation of the following list of grades: 80 75 91 60 79 89 65 80 95 50 81 Note: The average x_ave (or mean) of a given set of n number x_1,x_2,…..,x_n is given by: x_ave=(x_1+x_2+x_3+⋯+x_n)/n The standard deviation is given by: σ=√((∑_(i=1)^(i=n)▒(x_i-x_ave )^2 )/(n-1)) DO not use built-in functions to calculate the mean and the standard deviation. Write a user-defined function that arranges the digits of a given (positive) number in a row vector in the same order as they appear in the number; the function should also arrange the digits in the decimal part in a different vector. For example, if the number is 2645.12, the vectors should be [2 6 4 5] and [1 2]. The whole number can be from 0 to 10 digits long and the decimal part 0 to 6. Check the validity of the function using a few numbers of your choice. A fenced enclosure consists of a rectangle of length L and width 2R, and a semicircle of radius R, as shown in Figure. The enclosure is to be built to have an area A of 1600 ft2. The cost of the fence is $40 per foot for the curved portion, and $30 per foot for the straight sides. Determine the values of R and L required to minimize the total cost of the fence and the minimum cost using calculus approach. A water tank consists of a cylindrical part of radius r and height h, and a hemispherical top. The tank is to be constructed to hold 500 meter3 of fluid when filled. The cost to construct the cylindrical part of the tank is $300 per square meter of the surface area; the hemispherical part costs $400 per square meter. Determine the radius that results in the least cost and compute the corresponding height and the cost using graphical approach. Verify your results using the calculus approach.

EGR 140 Scientific Programming Assignment # 7 Spring 2017 Use MATLAB to solve each problem by writing script files; copy and paste the script file AND the results in the Command Window and/or plot in the Figure Window to a WORD document that has your name and section in the headers of each page and the page number in each footer. Edit the output to remove extra lines and empty spaces. The script files SHOULD have comments for easy readability; take a print out of the Word file and staple before submission. Due by 3 PM on April 11, 2017. Write a used-defined function that calculates the average and the standard deviation of a list of numbers. Use the function to calculate the average and the standard deviation of the following list of grades: 80 75 91 60 79 89 65 80 95 50 81 Note: The average x_ave (or mean) of a given set of n number x_1,x_2,…..,x_n is given by: x_ave=(x_1+x_2+x_3+⋯+x_n)/n The standard deviation is given by: σ=√((∑_(i=1)^(i=n)▒(x_i-x_ave )^2 )/(n-1)) DO not use built-in functions to calculate the mean and the standard deviation. Write a user-defined function that arranges the digits of a given (positive) number in a row vector in the same order as they appear in the number; the function should also arrange the digits in the decimal part in a different vector. For example, if the number is 2645.12, the vectors should be [2 6 4 5] and [1 2]. The whole number can be from 0 to 10 digits long and the decimal part 0 to 6. Check the validity of the function using a few numbers of your choice. A fenced enclosure consists of a rectangle of length L and width 2R, and a semicircle of radius R, as shown in Figure. The enclosure is to be built to have an area A of 1600 ft2. The cost of the fence is $40 per foot for the curved portion, and $30 per foot for the straight sides. Determine the values of R and L required to minimize the total cost of the fence and the minimum cost using calculus approach. A water tank consists of a cylindrical part of radius r and height h, and a hemispherical top. The tank is to be constructed to hold 500 meter3 of fluid when filled. The cost to construct the cylindrical part of the tank is $300 per square meter of the surface area; the hemispherical part costs $400 per square meter. Determine the radius that results in the least cost and compute the corresponding height and the cost using graphical approach. Verify your results using the calculus approach. A ceramic tile has the design shown in the figure. The shaded area is painted black and the rest of the tile is white. The border line between the red and the white areas follows the equation: y=Asin(x) Determine A such that the area of the white and black colors will be the same.

For this assignment, you will compose a letter designed to recruit students to join and support the agenda of one of three nonexistent student organizations that, were they to exist, would likely be very unpopular. The student organization for which you will be recruiting is determined by your last name: The first letter of your last name is… Your student organization assignment is… A – F The SETS Collective: SETS (Skip the Elevator, Take the Stairs) is dedicated to energy conservation on campus, particularly by eliminating elevator usage by pedestrians in any buildings on the UT-Austin campus. G – N O – Z Your recruiting letter must include eight (8) different persuasive strategies. Each strategy must be used in the service of encouraging students to join the organization and/or endorse its cause. In addition to your recruiting letter, you will also submit a commentary describing the different strategies you used in the recruiting letter. In this course, we utilize the TurnItIn tool. This service helps educators prevent plagiarism by detecting unoriginal content in student papers. In addition to acting as a plagiarism deterrent, it also has features designed to aid in educating students about plagiarism and importance of proper attribution of any borrowed content. For more information, please visit http://turnitin.com/. Below are a series of requirements for the paper assignment. Failure to satisfy these requirements will result in substantial point penalties. Also, failure to abide by the academic honesty policy described in the syllabus and maintained by the CMS department, the Moody College of Communication, and/or The University of Texas will result in a grade of F on the assignment and referral to the Dean of Students. Assignment Requirements • You must portray yourself as a recruiting officer (or Secretary of Recruitment) – not the President, VP, etc. – of the organization described in your letter. As a recruiting officer, you are not authorized to offer any rewards or bribes (gifts in the form of sports tickets, free meals, etc.) to people as an incentive to join the organization, nor are you allowed to make up fictional incentives (e.g., OBC students will enjoy an opportunity to participate in international conferences). Your letter should focus exclusively on the merits of joining the organization based on commitment to its cause. • Assume that organization has just been formed – i.e., do not portray it as having existed prior to the Spring of 2017. • You may also assume that there are currently only three members of the organization, the president, vice-president, and yourself (the Secretary of Recruitment). You CANNOT claim that there are “many members.” • You must use the following format for the recruiting letter AND the commentary: 12-point Times New Roman font, single-spaced (NOT double-spaced) on 8.5 X 11-inch white paper with 1-inch margins on all sides. • The recruiting letter must be no shorter than 2 nor longer than 3 pages; the commentary must be no longer than 2 pages. • Your recruiting letter must include only 8 (eight) DIFFERENT strategies discussed in the lectures and/or readings. You may use any principle/theory we have discussed EXCEPT for balance theory (which is too obvious) or deception (which isn’t persuasion per se). • Your commentary must identify the name OR what you did for of each strategy (e.g., Door In Face or Foot In The Door) used in your letter and describe the specific purpose(s) the strategy was used to achieve. At a minimum, your description of each strategy should consist of at least two complete sentences (16 sentences total). • Each strategy explanation in your commentary should be bulleted or numbered for easy identification • You may not lie under any circumstances. Lies include falsifications and/or distortions of the truth about the student organization (e.g., SURF is endorsed by the Fellowship of Christian Athletes). Also, you may not offer recruits bribes in any form (tickets, discounts, free food, cash, etc.) as an incentive for joining the organization. • Your completed assignment (recruiting letter + commentary) must be turned in on April 13th (a Thursday) at or before 9:30 a.m. Grading Rubric We will use the following rubric to evaluate and grade your letter + commentary.
