Looking for a high accuracy 3D graphing program

AI Thread Summary
A user is seeking a high-accuracy program for drawing 3D parametric curves, specifically for large variable inputs like f(10^8). Previous attempts with math.uri.edu and Ti-Nspire resulted in unsatisfactory, jagged curves. Recommendations include pocketCAS for iPad, which produces smoother curves, and SciLab, a free alternative similar to MatLab. The discussion clarifies that the focus is on plotting parametric curves rather than surfaces. The user is looking for further suggestions or solutions to improve accuracy in Ti-Nspire.

Hi PF/math !

I've been searching for a program which will draw 3d parametric curves accurately for large variables, eg. f(10^8).
Ive tried www.math.uri.edu and Ti-Nspire (the latter may or may not have a setting for the accuracy), but both tend to turn what should've been a smooth curve into an angled nightmare.

If anyone knows a decent program or how to fix the thing in Ti-Nspire, please let me know!

Thank you for your time and help

I use pocketCAS on the iPad and it seems to generate pretty smooth curves.

Can you tell us what surface you're trying to plot?
 
i'ts not a surface, it's a parametric curve. 3 independent functions, one for each dimension.

SciLab? It's like MatLab... but it's free. I love SciLab...
 

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...

Thread 'Non-orthogonal bases'

Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...

Thread 'A fully new path to prove Riemann Hypothesis'

For original Zeta function, ζ(s)=1+1/2^s+1/3^s+1/4^s+... =1+e^(-sln2)+e^(-sln3)+e^(-sln4)+... , Re(s)>1 If we regards it as some function got from Laplace transformation, and let this real function be ζ(x), that means L[ζ(x)]=ζ(s), then: ζ(x)=L^-1[ζ(s)]=δ(x)+δ(x-ln2)+δ(x-ln3)+δ(x-ln4)+... , this represents a series of Dirac delta functions at the points of x=0, ln2, ln3, ln4, ... , It may be still difficult to understand what ζ(x) means, but once it is integrated, the truth is clear...
