1. longest, shortest, and cross reference list are now individual components. see here

2. Look at gh math and trig components, Im pretty sure it can do all math

3. maybe your file is to big

4.

ALL MATH? http://mathworld.wolfram.com/letters/A.html :-p

In all seriousness, can you explain what you're trying to use differential calculus for? I've created some definitions that took advantage of derivatives or integrals and the field components make use of iterative methods for solving differential equations, but differential calculus is a pretty broad field.

^^I think it's often easyer it you know the math behind. 

file from the

https://www.dropbox.com/s/wfb7faod3kuez3a/Facet_beta_2.gh

f(x,y)=x^2-y^2

f'(x,y)=2x-2y (to find the tangent plane to a point on a the surface)

.. It would be nice if grasshopper did it automatic.

Correct me if I'm wrong, but you can get the tangent plane (frame) using the Evaluate Surface component.

I'm still pretty much a grasshoper and rhino noob ;-) hehe

But I've tried and it wouldn't work :-S .. Maybe because I used surface from point !?

Javier is correct - the evaluate surface component gives you a plane tangent to a surface at an evaluated point. The trick, and perhaps this is what was tripping you up, is that by default the range of coordinates on a surface are not determined in terms of X and Y but in U and V, and it's usually helpful to "reparameterize" the surface in order to ensure that the UV range is from (0,0) to (1,1).

@Michael Pryor

1. NICE! :-D
2. I don't think so.. :-S

3. nope same file: https://www.dropbox.com/s/wfb7faod3kuez3a/Facet_beta_2.gh

4 ..

5 thanks for the quick response ;-)

A way to do differential equations is the following, using four times the "evaluate" component.

On the lim+ the function just adds 0.000001 to the input number.

f(x) can be whichever function.

can you upload this code?
