Project 1: Limits

Instructions

Use Winplot and Google Docs to create a document with four problems on it:

1. A problem similar to problems 1.3.3-5.
2. A problem similar to problems 1.3.7-10.
3. A problem similar to problem 1.4.2.
4. A problem similar to problems 1.6.3-8.

Additional Notes

• Add your names at the top of the document under the title.
• Include instructions with each of the problems; don’t just create a graph or describe the graph.
• Include an answer key at the end of the document. Questions 2 and 4 will have many possible answers, include one of them in the answer key.

To submit the assignment, click the Share button in Google Docs and change it so that anyone with the link can view the results. Then copy the share link and email it to the instructor at james@richland.edu with an appropriate subject and the names of the people in the group. Only one person per group needs to submit the project.

Winplot Tips

File Menu

• When appropriate, use Image size to create a square document. The measurements are in centimeters. While 16.5 cm will make it fill the entire page horizontally, it will also take a lot of space vertically. You may want something smaller like 11.7 or 8.1, which will allow two side-by-side images.
• Use Bitmap to clipboard to capture the image so you can paste it into Google Docs. The regular copy to clipboard doesn’t work.
• Be sure to Save your graphic so that you can re-edit later if you need to do so.

View Menu

• Use Grid to control the visibility of the grid, axes, tick marks, and labels. I recommend using a rectangular grid with dotted lines in all four quadrants. Check the scale box to show the numeric labels on the axes.
• Use View to control the domain and range of the image.

Btns Menu

• Use Text to add labels to the graph. Use the right mouse button to add or edit text and the left mouse button to drag it and change its position.

Google Docs Tips

Google Docs

• Increase the font size on your document. The equations are the size of your normal font, but that may be too small to see the mathematical expressions while editing them. You can change the font size and then update the Normal text style to match. Alternatively, you can highlight the entire document and change the font size, but this may not apply to text added later.
• Click the Share button at the top right and change who has access so that anyone with the link can view the document. Then you can just submit the link.

Equations

• Use Insert > Equation to insert an equation
• Create the structure before you use it. For example, click on the fraction template before typing the numerator.
• There are some keyboard shortcuts, most notably the ^ and _ give you superscripts and subscripts.
• Matrices are not supported. That might not sound like a big deal, but the trick to displaying piecewise functions is to create a matrix to use as placeholders. In fact, multi-line equations are not supported either. Basically, you don’t want to use Google Docs for serious mathematical content, but it will allow for collaboration.
