update: 17th January 2014

A zipped Casio FXI
file containing all of the 32 programs listed below.
The file can only be opened and transferred to a
Calculator using the Casio FX software and an interface
cable.

Line to Plane
(253Kb) ** NEW JANUARY
2014

This is a
new program for the fx-7400G. It calculates the 3D
co-ordinates of a point at the intersection of a line
(defined by 2 points) to a plane (defined by 3 points).
Useful if trying to co-ordinate a hidden point (where it
is not possible to measure a distance).

A program
listing and explanation is also included

A pdf
document illustrating how the programs work along with
some examples. Thanks Cliff for spotting the
