Things to do -- 6/17

Today is picture day, wherein we work in lab and learn how to take pictures with Snappy and process them for use in LaTeX (postscript) and HTML (web page) documents. Here is a description of how to use Snappy to make class rolls for your web page.  The 'lecture' will be conducted in the lab, and will go on at the same time people are getting their pictures taken (so expect some cacophony).  The same injunction mentioned in yesterday's todo about thinking of and trying as many as possible other things to do than are on this list applies today (and for the rest of the workshop).

First download the zipfile day3.zip to D:\chisel\tmpdir.  Recall you do this by clicking on the link and then choosing the option save to disk  in the box that pops up.
Next open a TeXShell.  It will open open in d:\chisel\tmdir.
Now unzip the zipfile day3.zip with the command unzip  day3.zip.  A directory day3 is created in tmpdir and the files are stored in there.  Go down into that directory with the command cd day3, and do a dir /w to see a listing of the files there.   One of them is a latex source document mapgrap.tex.   Another is a maple worksheet qanda.mws.

Problem:  Produce a quiz1.ps (using latex and dvips) and inspect with gsview32 to see the pictures that are in it.  We want to replace the graphics with some others that we will generate using Maple.   So  from the start menu click on the Maple icon to start Maple and open the worksheet qanda.mws.   This worksheet explains a quick and dirty way to generate  eps graphics to replace those that are included in mapgrap.tex   Work thru the problems in that  worksheet.
 

Now that we have a way of producing color eps graphic files using Maple, lets look at the file  gdata.tex in day3.     Latex and dvips it to get a postscript file gdata.ps.  Now use gsview32 to look at gdata.ps and  wordpad to look at  gdata.tex.   Notice how the Title, author, and date are generated.    Change the author to Patrick Henry and the date to July 4, 1775.   Note how the table is produced.  Change the temperate units from Celsius to Fahrenheit (don't make the numerical conversion).  Put a double line around the outside of the table.    Go ahead and work Problem 1.   Bill Hill will be showcasing how to use the Calculator Based Laboratory equipment to collect data and how to analyse it with a calculator on Friday.
 

Problem:   Note that one data point [1,4.9] is plotted in the graph.   You could go ahead and plot the rest of them in the same way, but you probably wouldn't be able to connect the dots' because of the restrictions on the directions a line can go in the picture mode.  An better way would be to use Maple to generate a broken line graph which you overlay on the graphpaper.  Try something like this in a Maple input cell
> ti := [0,1,2,3,4,5,6,7];
> tm := [2.3,4.9,4.2,1.5,1,3.2,4.1,1];
> bill:= plot([seq([ti[i],tm[i]],i=1..nops(ti))]):
> plotsetup(ps,plotoutput=`d:\\chisel\\tmpdir\\day3\\bill.eps`,
> plotoptions=`color,portrait,noborder`);
> bill;
> plotsetup(default);
Then include bill.eps (using includegraphics) in the picture which draws the time temperature graph paper.  You will have to scale the broken line to make it fit correctly.

There is also a file called test.tex which shows how to put graph paper over photos,
