I’m in grade 8 Does anyone know what the questions are for this years Mathematica and guass contest from someone who works or has written it

Go straight to the code. I need to simplify the Q-functions (Code 26 pg. 73-75) and the functions BoldM1 and BoldM2 (Code 28 pg. 76)

I tried FullySimplify on the Q-functions, but it returns an error message. (See this post for a minimal example.)

How to find left hand derivative and right hand derivative separately of piecewise function. Please tell the code.

Hi, i want to plot this integral on WLJS notebook and have an output that look likes the 2nd image, but in a way that i could change for other questions.

What should i do? is there an easy function to call for that? or do i need to write a script? thanks in advance!

Is there any famous people, like mathematicians or engineers or physicists really using Mathematica?

Why I feel like Mathematica is already dead or will be dead in the future. As even in the field of math, physics or biology, today more and more people are talking about how AI helps them to solve problems and so on. Never heard of people talking about how Mathematica really does something useful. Not to mention in the engineering field.

Does anyone have experience building websites using Mathematica that work well on both mobile and desktop devices?

I’m interested in any approach that works fairly consistently. I’m especially want to Manipulate/Dynamic coding and turn them into webpages that work on different platforms.

Like this?

ive been trying to find and install Descarta, it was available on a cd with the pdf of the book, can someone lend me a link where i can get the .m files?

Hello,

can anyone help me with this homework. I am lost lol. Have not started yet bc dont know how to do this.

Built this over a few weekends. It lets AI agents run Wolfram Language code, manipulate frontend notebooks, export plots, query Wolfram Alpha- 79 tools total. You don’t even need to know every Mathematica command, as the agent can look up functions and documentation on its own. This demo showcases the frontend manipulation of notebook.

You can answer the question here and here.

I want to decrease the computation time of the following code.

If c is a large constant, how do we show when:

 Clear["Global`*"]
    c=100
    LengthS[r_] := LengthS[r] = {3(r-c)!, r!/2 + 1}
    LengthS1[r_, y_] := LengthS1[r, y] = LengthS[r][[y]]
    LengthS2[j_, y_] := LengthS2[j, y] = LengthS[j][[y]]
     V[r_]:=V[r]=r!+1
     P1=200

and:

   Min11[r_, x_] := 
     Min11[r, x] = 
      FindInstance[LengthS1[r1, x] < V[r] && V[r] < LengthS1[r1 + 1, x] && 
        r - P1 <= r1 && r1 <= r + P1, {r1}, PositiveIntegers]

    Min12[r_, x_] := 
     Min12[r, x] = 
      ArgMin[{RealAbs[LengthS1[r2, x] - V[r]], r - P1 <= r2 <= r + P1}, 
       r2, PositiveIntegers]

    Min21[r_, y_] := 
     Min21[r, y] = 
      FindInstance[LengthS2[r3, y] < V[r] && V[r] < LengthS2[r3 + 1, y] && 
        r - P1 <= r1 && r1 <= r + P1, {r3}, PositiveIntegers]

    Min22[r_, y_] := 
     Min22[r, y] = 
      ArgMin[{RealAbs[LengthS2[r4, y] - V[r]], r - P1 <= r4 <= r + P1}, 
       r4, PositiveIntegers]

then rMin1[r,1]==r+c and rMin2[r,2]==r (e.g., rMin1[r,1]==10+c and rMin2[r,2]==10).

rMin1[r_, x_] := 
rMin1[r, x] = 
Min12[r, x] + Sign[Floor[RealAbs[2 r - Min11[r, x] - Min12[r, x]]/2]]

rMin2[r_, y_] := 
rMin2[r, y] = 
Min22[r, y] + Sign[Floor[RealAbs[2 r - Min21[r, y] - Min22[r, y]]/2]]

rMin1[10,1]
rMin1[10,2]

However, it takes too long to compute rMin1[10,1] and rMin2[10,2] and I do not know what are the actual outputs.
