Excel
can be used just not for calendars or planners. It also comes into play
when used as math tools. It would prove more useful when combined with
google calculator, showing how the trigonometric function
is used to make calculation with various degrees on triangles.
Here is Excel Trigonometry:

An estimated "58.28252559 degrees"  Google Search shows
that the golden ratio plays a role in the golden rectangle.

The golden ratio is now used to draw the golden triangle and the pentagram on the same spreadsheet.
phi  (((1 / phi) * (1  ((1 / phi)^70))) / (1  (1 / phi))) = 0 is not verified by what I figure out with this spreadsheet on my Excel Trigonometry.

"Phi Figures"  a set of figures calculated with phi and trigonometric function 
is added on this spreadsheet.  November 21, 2006

The Pentagon and The Pentagram

A group of 12 connected pentagons make a dodecahedron.
A pattern was designed and drawn on this spreadsheet to cut and fold to make a dodecahedron dice.
Thus polyhedron like dodecahedron will be explored with Excel to use polygon like pentagon as building blocks.

PhibyPhi Square  as there seems to be no naming established for this, I would like to call this Golden Square.

Exploring Pi with Trigonometry
PHI^n2 + PHI^n1 = PHI^n  This is Fibonacci Golden Ratio as shown in the spreadsheet.
Try entering "=PHI" or "=PI" and "=SIN( *degrees)" on the "PHI Park" sheet.
