I'm straggling with Maple. The main purpose is to plot f(x,y)

I have two for loops for x and y  coordinates and I want to plot f(x,y)

for i from 1 to 5 do
for j from 1 to 5 do
xxiI]:=evalf(xx[0]+II*0.1):
x:=xx[i]:
yy[j]:=evalf(j*0.1):
 y:=yy[j]:
here I should type yhr function that depends on x and y( how can)

od:od:

and then i put the list of  points:=seq,( x,y,f(x,y) ??

and then surfdata(ponts)

is my logic right???

hello friends,

how can i find analytical solution of the

dT/dt = alpha * d^2T/dx^2

T(t,x)

t: time, x: space

with maple for given temperature conditions and initial condition

I was told that to obtain explicit values for an expression of a RootOf expression, I should use the allvalues command. However, when I use it with RootOf(expr, index=1),RootOf(expr, index 2), and so on, I use allvalues and get no explicit solution. I even tried to use allvalues, explicit.

Thanks.

Hi

The world has fallen over my head this morning when I discovered that the SAME maple input file, running on the same computer, had given different results. How can that  be possible???

Thanks.

S.

Could I please get help with this maple assignment? No idea where to even begin!!

I have the following solution with Maple 13:  RootOf((-4+4d)_Z+(4-4d)_Z-3d+2).

I understand that to obtain an explicit solution to the complex roots, I have to use evalf.

So when I write evalf(%) or evalf(RootOf((-4+4d)_Z+(4-4d)_Z-3d+2)), Maple returns the same complex root.

Hope you can assist me.

Thanks.

I came across a quite interesting problem as seen below  (and no it is not homework.)

I am just interested in how such a problem would be solved ?!

F(x) is a
