Refining Your Data StoryTo deliver an effective Board Brief and presentation, you will need to display your data to decision-makers in a way that is easy to understand. Respond to the prompts below:What are the most critical elements of your data story that need to be communicated? Explain.How will you organize and share your data so that it tells a clear and compelling story? (See p. 107 of Davenport & Kim for a list of types of visual graphics used to present data)Select two data display techniques discussed by Duarte in Chapter 6 and/or Chapter 7 and use them to present two important data sets from your analysis.
Obtain the general solution of the following DEs: i. y′′′ + y′′ − 4y′ + 2y = 0 ii. y(4) + 4y(2) = 0 iii. x(x − 2)y′′ + 2(x − 1)y′ − 2y = 0; use y1 = (1 − x) iv. y′′ − 4y = sin2(x) v. y′′ − 4y′ + 3y = x ; use y1 = e3x vi. y′′ + 5y′ + 6y = e2xcos(x) vii. y′′ + y = sec(x) tan(x)
