Week 2 Homework ENGR 112 Arrays and plotting Learning Objectives: You should accomplish the following: Understand how to create arrays, calculate with them, and extract data from them. Plot the results of calculations. Be able to split up plots into multiple windows Plot multiple things in the same window with different colors and attributes. Homework Guidelines: 1) Use example scripts from online for help plotting and vectors. 2) Save scripts as “HW2Script1.m” for problem 1, “HW2Script2.m” for problem 2, etc. Specific Coding Notes: Plotting – Label axes (with units when known), use titles, and use legend when plotting more than one thing on a graph. Example: NO 😊 YES 😊 Warnings and Errors – You may see orange and red bars on the right-hand side of the editor. Orange bars are warnings and red bars are errors. Hovering with the cursor over a par will show you the problem. Example:

Week 2 Homework ENGR 112 Arrays and plotting Problem 1 a) Plot the following mathematical function in the domain -10 ≤ t ≤ 7 in increments of 0.004. Assume that the x-axis is time measured in seconds, and the y-axis is distance measured in meters. Print the minimum and maximum values of y for that range of ts, and the t-values that produce the minimum and maximum values using the proper matlab functions. Label the axes with time in seconds (t) and distance in meters (y). a. Hint: Look up the different versions of the function min/max. b) Check the minimum value against the analytic solution (hint: minimum and maximum values occur when the derivative is zero).
