In each of Problems 5 through 18: (a) Determine all critical points of the given system of equations. (b) Find the corresponding linear system near each critical point. (c) Find the eigenvalues of each linear system. What conclusions can you then draw about the nonlinear system? (d) Draw a phase portrait of the nonlinear system to confirm your conclusions or to extend them in those cases where the linear system does not provide definite information about the...

In this exercise you will be designing a program in c++ that does the following: Prompts the user for a file name and then shows the user with the number of word in the file. The program should then allow the user to repeatedly specify a number and the program should show that word in the file. For example, if the file contained the text: Hello. This is the text that is contained in this file. A sample run of...
Using R code: A researcher collects data on the relationship between the amount of daily exercise a person gets and their percent of body fat. She is trying to see if exercise (X) can predict percentage of body fat (Y). The following data were recorded: Individual 1 2 3 4 5 Daily Exercise (min) (X) 10 18 26 33 44 % Fat (Y) 30 25 18 17 14 a. Draw a scatterplot that represents this data set with linear and lowess...

PROBLEM #1: ELECTRIC FIELD VECTORS As part of your internship with a local power company, you have been assigned to a team reviewing published research about the effects of electric fields on human health. To evaluate the merits of apparently conflicting research, you need a computer program to simulate the electric field due to complicated charge configurations. Your team leader has assigned you the task of evaluating such a program. To test the program, you...
