hi

how can I download Fourier series package?

Hello Primers

I am doing some homework with the software Maple 2015 where I am supposed to design a lamp through creating some line segments and a circle in a 2d coordinate system. But my question is, how do I add a third dimension and rotate all these line segments around the y-axis, so I can get an idea of how it looks like in 3d?

Here is a picture

Thanks in advance

Dear Friends

I need to arrange legends from 2 to 1.2

Please hint me

Thanks

restart:
e := x*t*(E[c]-E[m])/((2*(x+2))*(x*E[c]+E[m])):
EZ := (E[m]-E[c])*((t-2*z-2*e)/(2*t))^x+E[c]:
assume(x > 0):
d := int(EZ*z^2/(-nu^2+1), z = -(1/2)*t-e .. (1/2)*t-e):
R := simplify(subs(E[c] = k*E[m], d/subs(x = 0, d))):
LS[1.2] := solid:LS[1.4] := longdash:LS[1.6] := dash:LS[1.8] := spacedash:LS[2.0] := dashdot:
for k from 1.2 by .2 to 2.0 do
p[k] := plot(R, x = 0 .. 5, color = black, axes = framed, font = [Times, 13], size = [650, 550], resolution = 1200, legendstyle = [location = right], legend = ['E[c]/E[m]' = k], linestyle = LS[k], thickness = 2, labels = ['n', 'P[FG]/P[Metallic]'], labelfont = [Times, 14], tickmarks = [10, 15])
end do:
with(plots):
display({`$`(p[1+.2*m], m = 1 .. 5)});

Hi,

Is it possible to use the command MatrixFunction with two matrices as:

with(LinearAlgebra):

A := Matrix([[-13, -10], [21, 16]]); B := Matrix([[3, 0], [21, 16]]);

BesselY(A,B) ?

In the maple help we can do the calculation only for one matrix as:

MatrixFunction(A, sin(x), x);

Thank you

how to make below can be successfully run?

normaldiff := proc(f1)
return limit((subs(x=x+h,f1)-f1)/h, h=0):
end if:
recurdiff := proc(f2)
if f2 = 0 then
return 0:
end if:
if f2 <> 0 then
return limit((subs(x=x+h,normaldiff(f2)+recurdiff(f2))-(normaldiff(f2)+recurdiff(f2)))/h, h=0):
end if:

f := x;
normaldiff(f)+recurdiff(f);

expect return 1, is like normal diff

Hi I am reading this help document

http://www.maplesoft.com/support/help/Maple/view.aspx?path=SpaceCurve

and I cannot get maple to plot the same exact graph on that page, I receive this error

http://prntscr.com/8gzpt4

It only lets me plot 3 dimensional curves http://prntscr.com/8gzsry

When I downloaded the help document, the command executed. I cannot get it to work on my worksheet.

I even tried adding with(Student[VectorCalculus] ): and that did not help. 

I am clueless why this is not working.

Is there a way to upload a maple worksheet so you can see the error.

Hi, I'm new to Maple and have been trying to solve the below curve intersection. But the answer I am getting from Maple is incorrect and does not tally with the plot when drawn on excel, am I doing something wrong ???  (the intersect should be around x=93.9)

restart;
eq1:=y=86:
eq2:=y=-0.0000054527x^3+0.010903836x^2+0.0714244709x+74.18816:
sol:=solve({eq1,eq2},{x,y});

Hi Maple People,

I want to plot two parametric curves on the same plot.  Namely,

x1 = t^2 + t + 41; y1 = t^2 + 40;

x2 = 4*t^2 + 163; y2 = 2*t^2 + t + 81;

where -3 < t < 3

What is the syntax for this?

Regards, Matt

Hey,

i am trying to put u[0](zeta):=0 in maple but it gives an error, however it accepts u[0]:=0 but i have to involve zeta in it. help please.

 here is my program 

bc1 := u(x, y)-0;
dydxf := (1/2)*(-u[m+2](zeta)-3*u[m](zeta)+4*u[m+1](zeta))/h; 
bc1 := subs(diff(u(x, y), x) = subs(m = 0, dydxf), u(x, y) = u[0](zeta), x = 0, bc1);
eq[0] := bc1;
u[0](zeta):=(solve(eq[0],u[0](zeta)));

on pressing enter a new window opens of title

clerify expression.

parts of expressions are ambigous. please select one of the suggested meanings.

function defination or remember table assignment.

then it gives the error below
Error, unable to parse

:=(Zeta)->(solve(eq[0],u[0](Zeta)));

Hi,

why the output for this program just only "print BChange" not a matrix?

Der:=proc(A,n)

local i,j,k,t,S1,S2,l,C,sols,eqns,BChange;

C:=matrix(n,n); BChange:=matrix(n,n); eqns:={};

for i to n-1 do

  for j from i+1 to n do

    for l to n do

      S1:=sum(A[i,j,k]*C[k,l],k=1..n);

      S2:=sum(A[k,j,l]*C[i,k]+A[i,k,l]*C[j,k],k=1..n);

      eqns:=union(eqns,{S1=S2})

    end do

  end do

end do;

sols:=[solve(eqns)];

t:=nops(sols);

for i to t do

  for j to n do

    for k to n do

      BChange[j,k]:=subs(sols[i],C[j,k])

    end do;

  end do;

end do;

print (BChange)

end proc:

> A1 := array(sparse, 1 .. 2, 1 .. 2, 1 .. 2, [(1, 1, 2) = 1]):
> Der(A1, 2);
                                                                   print BChange

Can someone please advice me on this?

thanks

Bad title, I know. 

Suppose I have solved an ODE numerically, say for a function f(x). Now, I want to solve another ODE numerically, given by

diff(g(x),x) = f(x)*g(x)

I want to solve for g(x), and I only know f(x) from the numerical solution I obtained in the first ODE. How do I implement this in Maple?

I attached a worksheet with my naive attempt with this simple example. Basically I do not know how to set up the differential equation which I would then input to dsolve. 

ode.mw

Thanks!

why when maple cant solve the following?

pals ,i have problem when i want to refer to a number of an equation :

num.mw

thanks

Hi

there are two style to write on the worksheet mode (Text and Math)

I prefer the  writing  on  (text mode ) by pressing (f5) , but my  problem is when I press Enter to pass  to a new line on my page which has (test style). the style of page changes to (math).

my question is How can I fix a style of the worksheet page?
