Request for The Golden Ratio. - douganc - 08-06-2015 11:42 PM
Hp Prime Software Team.
1: Please add the Golden Ratio (1.618 ect.) to the Maths Constants Menu on the Hp Prime soft keys.
2: Also please add a photo of a Renaissance Painting that demonstrates the early use of geometric perspective to the built in photo library.
This would be very useful for Artistic Students who are studying Perspective and Geometry.
To get them interested in Maths Class.
Please store the ratio to fifty decimal places.
Thank You
Colm

Hello!
For 1), try
(1 + sqrt(5)) / 2
RE: Request for The Golden Ratio. - retoa - 08-07-2015 10:02 PM
Or
(sqrt(5) - 1) / 2
if you need 1/phi
No need for a specific constant if you know what the Golden Ratio is. It's not like pi, e or some physical constants you have to know because there is no easy way to calculate them.

Thank You for Help.
Still it would nice to have Phi on soft menu, to quickly call it.
and in Catalog also.
We can Dream as Artists Do .......

you could define a function.
Use Define (shift D):
name -> phi_golden (phi is Euler function, already "occupied", see here)
function: (1+√5)/2
Then you find it in Toolbar -> User -> User functions
Try it

Ignore the question marks, don't know where they came from.
