What's the relationship between them?? Exercise 2.7 Use slopefield to draw a direction field for the differential equation y' = cos(x) + - sin(y), and then draw some solution curves on the resulting direction field using drawode. Include your figure in your Word document. Now consider the system (13) dx/dt = = 1 dy/dt = cos(x) + sin(y) where x(0) = 0. Tell MATLAB to create a new figure using the figure command. Then use phaseplane to draw a phase portrait for the system (13), and plot a phase path on your diagram using drawphase; the y1start value represents x(0) and should therefore be zero, while the y2start value can be any initial value for y(0) of your choosing. Finally, try adding a few more phase paths using other values for y(0). Paste the resulting figure into your Word document. What's the relationship between your phase portrait figures and your direction field figure? [Hint: When you drew the solutions on your direction field, you should have picked several different starting values for x and y. Try drawing some phase paths on your phase portrait with the same initial values. Do the resulting curves match up?]

Problem 1: Logistic Regression Basics - Odds and Ends a) What is the equivalent odds for the probability 0.25? b) You are testing a new drug and have gathered binary data on whether the drug performed its desired effects. From the control trial, 102 people saw improvement with a placebo and 241 did not. With the drug, 67 people saw improvement and 82 did not. What is the odds ratio of these results? c) You've decided to determine the probability of a picture containing an animal on social media. On 6 different days, you look at 10 random pictures and record the number of pictures that contain at least one animal, and get the values {6,10,7,9,5,9}. Given these results, what is the MLE for the probability of a picture containing an animal?
