[racket-users] Interpolating Polynomial in Newton Form

Newton form. My understanding of functions that produce functions is limited to what’s in HtDP, and this example (I think) goes beyond that. Any tips or advice would be much appreciated! Cheers, Dave Yrueta -- You received this message because you are subscribed to the Google Groups

Re: [racket-users] Interpolating Polynomial in Newton Form

Yes, I can see at least two significant errors in my description. The first is in the sequence definitions. They should be list of constants (a0, a1… an) and a list of x-values (x0, x1,….x(n-1)) Similarly, the def of p(x) should read p(x) = a0 + a1(x - x0) + a2(x - x0)(x - x1) + a3(x - x0)(x

Please ignore previous post. Figured out the problem. My bad. On Oct 30, 2013, at 9:47 AM, Dave Yrueta wrote: > Hi All -- > > I pulled this from the Docs on plot -- > > (require plot) > > (plot (function (λ (x) (sin (* 4 x))) -1 1) >#:x-min -1.5 #:x-max 1.5

[racket] Problems with Plot

Hi All -- I pulled this from the Docs on plot -- (require plot) (plot (function (λ (x) (sin (* 4 x))) -1 1) #:x-min -1.5 #:x-max 1.5 #:y-min -1.5 #:y-max 1.5) -- ran it in Dr. Racket, and received the following error: "#%datum: keyword used as an expression" with "#:x-min" highlighted

[racket] Scribble and/or Latex?

ht learning Scribble might be a good route to take. I've poked through the docs a bit, and can't find any reference on math typesetting. Can that be done in Scribble? Or is Scribble not the right tool, and should I commit my learning efforts to Latex? Or both? Thanks! Dave Yrueta

Re: [racket] arrangements exercise

s, function contracts and function templates interact. If you allow the data definitions to shape the function templates, and are rigorous about ensuring the function designs conform to their contracts, the solution should fall into place. Good luck! Dave Yrueta On Jul 1, 2012, at 1:
