pjplot32   is the first release of my graphlotting tutor for GCSE maths.

It is written for and tested on  P.C.s running 32 bit windows 95 .
It has been written for use both at home and in the classroom  with 
the aim of teaching users how to plot graphs,from simple experimental
results to linear and quadratic functions. It contains help windows 
to explain each of the many plots and suggests simple rules for curve
sketching.  Also included is the ability to plot your own functions 
and solve simultaneous equations graphically.  Some trig functions 
are available for plotting at variable frequencies and amplitudes 
with modulation of two sine waves also available as an added 
extra.  

To install simply run setup from the archive after unzipping the file to 
the 'temp' directory or similar.  Please note that to reduce the size of 
the zip file in the simtel database you will need to also download the 
archive below which contains common run time files used by visual basic 
applications, if they are not already available in your windows/system 
directory.

They are available in a single zip from simtel at:

             /pub/simtelnet/win95/dll/vb40032.zip

this includes the following files which must be present on your system
 
  VB40032.DLL
  OLEPRO32.DLL
  MSVCRT40.DLL

Registration of pjplot32 will cost £9.99 payable to Mr P J Jensen,

This release is a shareware demonstration program which whilst not fully 
functioning will allow many of the above operations free of charge.  It is 
freely distributable in this form.
