i am implementing q-Laplace

http://perso.uclouvain.be/alphonse.magnus/gbang/qbook712.pdf

when there are quite many differentiation rules

how to do a function for a new kind differentiation like a maple do?

1.

qRacah := qhyperterm([q^(-x), alpha*q^(-x)/(gamma*delta)], [alpha*q], q, gamma*delta*q^(x+1)*t, k)*qhyperterm([beta*delta*q^(x+1), gamma*q^(x+1)], [beta*q], q, q^(-x)*t, k);

i use inverse laplace to transform ordinary generating function into exponential generating function

can not further evaluated

2.

i do not know whether x is main variable or q is main variable or both are.

ff := eval(subs(x=0, exponential_genfun));

How to give the different colors in implicit plot  and add legends my codes are 

with(plots):

g:=y*(1-1/(x^2+y^2)):

aa:=[g=0.1,g=0,g=0.5]:

implicitplot({seq(aa[i],i=1..3)},x=-5..5,y=0..2,legend="g=0.1,g=0,g=0.5",color=[red,blue,green],scaling=constrained);

i want to draw  a countour plot and i want the graph in the given below patter  and my codes are 

for Q=1, and Q=2 ,Q=3.2

F:= x^2+2*y^3+Q:
p1:=contourplot( F, x=0..1, Q=1,color=red):
p2:=contourplot( F, x=0..10, Q=2,color=blue):
display(p1,p2):

thanks in advance

Is there a function that will return the current orientation values in a 3dplot, or can anyone help me with this. I would like to display the orientation as I rotate a plot.

TIA

Does anyone know why the scale isn't matching what i asked for here?

Its a bit like this problem:

Hi,

I have a trigonometric series which contains 1D and 2D modes. It looks something like the following:

S:= Acos(mx)sin(nz) + Bcos(kz)sin(qx) + Csin(sz) for m,n,k,q,s=1,.....10.

I am iterested in obtaining the amplitudes of the 1D modes (i.e. C in the above expression). Is there a way to do this using the coeffs function? I would like to use this in such a way as to isolate the 1D modes from th series. Any suggestions?

Thanks for your help.

Hi, 

   I'm solving two equations and two unknowns with fsolve where there are multiple solutions (at most 3). I iterate this and my next set of solutions depends on the previous one. The problem is the the first solution (the only one I need) may be arbitrarity close to to the previoius solutions and fsolve skips it and finds the second solution. Any recommendations or ways of makign fsolve resolve arbitrarily close solutions?

Thanks,

Hi guys,

I have the following complex equation,

Az:=unapply((rhs(sol[2])*BesselJ(q,t2*r)+rhs(sol[3])*BesselY(q,t2*r))),r)

It gives a value which is constant for frequency upto 3000 Hz, i.e. if I run the solution again keeping all the values constant the result is the same  BUT   When I change the frequency to 15000 Hz, the equation still give me the result but every time its different when I run the program with constant values.

If I have  the following..or different numbers, but 2 different arrays I need to calculate sample mean & variance

Array A:=([1,1,1,0,0,3,2,4])

and

Array B:=([2,1,0,1,3,3,4,1])

what formula do I use to force Maple 16 to calculate the sample mean and the sample variance?

Hi

I want to plot a graph of Sin[x*Pi]*Exp[A*x], this works perfectly well for low A values but I want to try say A=10^2. Is there any way to plot this sort of function?

I need to use subscripts to define a system of equation and its respective variables. I do not encounter any problem when I use solve or Basis (with Groebner package) but when I tried to use RealRootCounting (with RegularChains and SemiAlgebraicSetTools packages), I got the following error message:

Error, (in RegularChains:-SemiAlgebraicSetTools:-RealRootCounting) invalid input: TRDnearsolve expects its 5th argument, vlist, to be of type list(symbol), but received [p[1], x[1], q[1], u[1]]...

Daniel Kahneman - Thinking Fast and Slow

1) A bat and ball cost $1.10.
2) The bat costs one dollar more than the ball.
3) How much does the ball cost?

x+y=1.1; x=cost of the bat, y=cost of the ball.
y=x+1; substituting for y
x+(x+1)=1.1;
2x=0.1;
x=0.05; the cost of the ball
y=1.05; the cost of the bat

The right answer is 5 cents.
The intuitive, appealing, and wrong number is, of course 10 cents.
