Lesson 20
Part III (Introduction to Differential Equations, continued)
We have one more type of ClassPad differential equation to try. For this type, nth order, we can only display solution curves based on initial conditions.
1. Inputting an nth Order Differential Equation

2. Inputting Initial Conditions

Part III
Practice Exercises
- Open the eActivity named L20_PartIII_a in the Lesson 20 folder.
- Follow the directions inside the eActivity!
- After you drag and drop all the required items, resize the graph window.
- With the graph window showing, get a screen capture. Paste it into your Lesson20 document (under a title of PART III).
- Note: You do not need to save your eActivities for Lesson 20.
- Open the eActivity named L20_PartIII_b in the Lesson 20 folder.
- Follow the directions inside the eActivity.
- After you drag and drop all the required items, resize the graph window.
- With the graph window showing, get a screen capture. Add two blank spaces following the first screen capture and then paste this one.
- Open the eActivity named L20_PartIII_c in the Lesson 20 folder.
- Follow the directions inside the eActivity.
- After you drag and drop all the required items, resize the graph window.
- With the graph window showing, get a screen capture. Add two blank spaces following the second screen capture and then paste this one.
Part IV
Reflection Exercises
You have just completed the twentieth lesson in ClassPad 101. Just one lesson to go! Please take a few moments to copy and paste the following three questions at the end of your Lesson20 document and answer them.
- Approximately how long did it take you to complete this lesson?
- Which activity did you enjoy the most?
- Did you find any part of this activity difficult to follow? If so, which part? Also, how did you overcome the difficulty?
Assessment 20: Introduction to Differential Equations
- Checkpoint: Your word processed document, titled "Lesson20", should contain the following activities:
- Three screen captures from PART I
- Three screen captures from PART II
- Three screen captures from PART III
- Three reflection questions with answers from PART IV
- Submit your Lesson20 document to your instructor for grading. Once your lesson is submitted, your lesson for ClassPad 101 “Introduction to Differential Equations” is complete.
