MTH229 Projects

These are a collection of IJulia notebooks to support the MTH229 class at the College of Staten Island

They can be cloned and run on a local jupyter or jupyterhub installation.

They can be run on the department's juliabox server.

They can be used within binder by clicking the link above.

Questions and Answers

These notebooks only contain the background details and many blank cells. New blank cells can be added through the Insert menu.

Question and answers are now presented and completed through WeBWorK.

There are a few idiosyncracies to be aware of when navigating between WeBWorK and the Jupyter interface:

• Most code examples are typeset in WeBWorK as though they appear in a terminal. A terminal displays the output of each command immediately after execution. In a notebook, when a cell is executed, all the commands are computed and only the last value is shown. (The use of @show or print(...) can be used to display intermediate values in a cell.)

• Copy and paste from WeBWorK into a notebook will usually be unsuccessful, as numbers in the font used to display computer markup do not copy as ASCII numbers into a cell. The numbers can be hand edited though.

• While Julia is very happy to express its output using scientific notation, WeBWorK is not happy to receive the exact output for an answer. Either replace e with E (as in 1.23e4 would be 1.23E4) or use decimals.

• For most questions with a numeric answer it is best to copy all 16 digits of output. Several digits after the decimal point are expected to match a correct answer (an absolute tolerance of 0.0001 is used). For numeric questions where an estimate is made, say from a graph, this is significantly relaxed.

• If the answer is to be a function, the automatic grader of WeBWorK is expecting just the rule of the function (an expression).
