Misleading hint on slide 43 "Exercise: Loops and Functions"

[GoogleCodeExporter]

What steps will reproduce the problem?
1. run the gotour and look at the slide 43 "Exercise: Loops and Functions"


What is the expected output? What do you see instead?
  The hint is misleading.  Looking at the provided Newton formula, there is z in denominator.  The hint suggest using z := 0.0 as a starting point.  This directly leads to division by zero.

  It'l be better to use another value for the hint.  For instance 1.0. or x/2.


What version of the product are you using? On what operating system?

   I think the last from repository.  I checked it out yesterday.

Please provide any additional information below.

I just clone gotour and create patch for this issue.  But it takes a time to 
know how all the development proces works and what to do.
