CIS 343 Homework #1 1. In the game of “craps” two dice are thrown and the outcome of a bet is based on the sum of the two dice. If you bet \$1 that the sum is “seven” then you win \$4 or lose your dollar. The probability that you win is 6/36=1/6, and P(loss) = 5/6. Find a rough range for a) 200 plays, (b) 20, 000 plays. You must show your work when you compute the SD of the box! [Hint: There are four steps in solving this problem. 1. You must first find the box model, the simplest model has six tickets in the box with some of the tickets +4 and others –1. You must determine how many of each of those two numbers are in the box. 2. Next find the Average of the box and the SD of the box, use “n” not “(n-1)” to compute the SD. 3. Third compute Expected(Winnings)=m•AveOfBox and SD(Winnings)=√m•SDofBox, where m is the number of plays. 4. Finally the Rough Range is Expected(Win)±SD(Win).] 2. Work out the average and SD for the following list: a) 1, 3, 4, 5, 7 Then work out the average and SD for the next list: b) 6, 8, 9, 10, 12 Use n-1 in computing the SD. Are you surprised by the answers? 3. Use “n” in computing SD’s for this problem. a) A list has 10 numbers, each number is a 1, or 2, or 3. If the average is 2 and the SD is 0, find the list. b) A second list has 10 numbers, each number is a 1, or 2, or 3. If the SD is 1, find the list. c) Can the SD be bigger than 1? [This problem is solved by trial and error. Think what center and spread mean! You do not need to use every number for every list. If you do not like the number 3, you may not have to use it] 4. Find the population standard deviation for the following four populations: a) 1, 2, 3, 4, 5 b) 1, 2, 3, 4, 5, 1, 2, 3, 4, 5 [Divide by 5 for the population in a), divide by 10 for the population in b).] c) 2, -1, -1, -1 d) 2, -1, -1, -1, 2, -1, -1, -1 [Divide by 4 for the population in c), divide by 8 for the population in d).]

MA 3351 – Fall 2015 Homework #4 Due Friday, 25 September 1. Use the method of variation of parameters to solve y′ = Ay + f (t) y (0) = y0 where (a) A =  −2 1 1 −2  f (t) =  t 1  y0 =  0 0  (b) A =  4 1 1 4  f (t) =  e−t t2  y0 =  1 −1  (c) A =  −4 2 1 −5  f (t) =  e−t t2  y0 =  1 0  Do all calculations by hand. Use diagonalization to compute any matrix exponentials. Be sure to take advantage of the properties of symmetric matrices when applicable. 2. Repeat problem 1 using Mathematica. Be sure to use MatrixExp instead of Exp when computing matrix exponentials. 3. Use the method of Laplace transforms to solve problem 1, using Mathematica to do the calculations. 4. Let A be the matrix A =  2 1 −1 4 . (a) A has a single eigenvalue l of multiplicity 2. Find it. (b) Find the eigenspace for l. Is A defective? (c) Let J be the Jordan block  l 1 0 l . By hand, find a matrix V such that AV = VJ. ADDITIONAL PROBLEMS ON BACK PAGE 1 5. Let J be the Jordan block J =  5 1 0 5 . The solution to y′ = Jy, y (0) = y0 is y (t) = eJty0; however, because J is defective we can’t use diagonalization to compute eJt. Instead, we can compute it using Laplace transforms. (a) By hand, find (Is − J)−1. (b) Find the inverse Laplace transform of (Is − J)−1. You may use Mathematica for this step. (c) Compare your result to eJt as computed by Mathematica’s MatrixExp function. 6. Consider the system y′ = Ay + f (t) with initial conditions y (0) =  0 0 1 0 0  where f (t) =  sin (pt) 0 0 0 0  and A =  −2 1 0 0 0 1 −2 1 0 0 0 1 −2 1 0 0 0 1 −2 1 0 0 0 1 −2  . (a) Use either Laplace transforms or variation of parameters (whichever you prefer) to solve the problem. You should use Mathematica to do your calculations; run FullSimplify on the results. (b) Plot y1 (t) , y2 (t), …, y5 (t) versus t over the interval t ∈ [0, 10]. Show all five functions on the same figure. (To see how to plot multiple functions on the same figure, see theMathematica examples I provided for you as well as theMathematica documentation.) 2

Engineering/Science and Public Policy Paper NOTE: This assignment is an individual Assignment. You could discuss with peers but your submission must reflect your opinions and be completed on your own words. As an engineer/scientist, public policies will directly impact virtually every issue of your professional life: design and construction, public safety, environmental quality, materials application – just to name a few. Appreciating the importance of this process will be a key factor to your success as an engineer/scientist. The purpose of this activity is to provide you with a better understanding of: • Public policy processes that impact engineers/scientist as they practice their profession • State and federal agencies and other legal authorities with jurisdiction over engineering/science matters • The role of engineers/scientist in creating technical solutions that benefit citizens and the environment. Assignment For one of the following four contemporary issues, do the following: a) Identify federal and state agencies / legal authority b) Discuss the engineering/scientific response c) Research codes & standards that are applicable or organizations that should oversee them d) Expand on the societal impact: cost vs. benefit Contemporary Issues for Assignment 1. Policy on Federal Reserve Bank’s Prime Interest Rate and Its Impact on Global Economy 2. Policy on Oil Price vs. Shale Gas/Oil and Its Impact on U.S. and Global Economy 3. Policy on Privacy/Security of Cloud Computing Systems and Its Impact 4. Policy on Biodiesel and Trends: Past, Present, and Future Guidelines a) The document should be in single space format. b) The minimum length is 500 words and the maximum length is 1000 words. c) List of references should be included in a separate page. Appropriate citations must appear in the body of the main document.
