hi  for example to calculate the following

residue((Psi(-z)+Eulergamma)^2*h(z), z = 2)

gives

3*h(2)+(D(h))(2)

but it possible to write 

as( Psi(2)+Eulergamma(z))*h(2)+(D(h))(2)

so that 

and Psi(z)+Eulergamma== harmonicNumber(z-1)

the result must be

harmonicNumber(2)*h(2)+(D(h))(2)

it is possible that Maple gives explit form of the values function avoid to calculate automatic.

thanks

Hello There:

I used to display module bodies with eval with former Maple version: it seems not to work with Maple 2015: any idea ?

Thanks in advance,

Jerome

Hi all,

I am considering a scenario in which I have, for example, four matrices, A, B, C, and D, which form a basis for all of the (numerical) calculations I am doing.  (For example, A + B = i*C, etc.)  Right now, if I add A and B, I get a matrix back whose elements are i*C, but I cannot get Maple to express it as i*C.  As a simple example, let:

A = (1 0 // 0 1 )

B = (0 1 // -1 0)

C = (i i // -i i)

Then A + B returns (1 1 // -1 1); I'd like for Maple to "intelligently" give iC.  So...how can I get Maple to expand a given matrix (A+B) in terms of a particular basis (here, simply C)?

Thank you.

3 different dia circular cheeses. same depth. minimize cuts such that its divided equaly among four people.

can be done in 3 cuts. can evem be done in 2

could some erudite richard provide maple solution to this Q. thx

reinstalled m18, i used to have an ini file, but it got deleted.

so i made a text file, called it maple.ini with the following text: 

interface(prompt=""):
e:=exp(1);
digits:=15;
HelpBGColor=255,255,224;
print("maple init loaded...");

I placed it

 C:\Program Files\Maple 18\bin.win

and

 C:\Program Files\Maple 18\lib

and

C:\Program Files\Maple 18\Users

it doesnt load when i load maple!

We find recent applications of the components applied to the linear momentum, circular equations applied to engineering. Just simply replace the vector or scalar fields to thereby reasoning and use the right button.

Hi, I know this has been asked ( and answered before) but when I installed this package and pressed ?globalsearch the help page is void.how do I get it?

Why does my Maple 2015 constantly pause to redraw symbols in pinned palettes?  Really seems to slow down my use of the program.  Had this problem in previous versions also.  Using OSX Yosemite latest version.

How to solve delay differential equations with Maple?

Example:

diff(x(t),t) = 3*x(t)^2 + 0.3*x(x-0.03)

Hello everybody,

I have an nx2 matrix of (t,w) , I need to fit a curve of the form of w = A(t-b)^c to the data. What I have already tried is to pick a value for b, then regress log w on log (t-b) linearly, which is not very accurate. I'd  greatly appreciate any comments that could help me to find the optimum values for A, b and c through regression methods.

Thanks a lot,

Haley

Hello everyone, 

I have a question regarding my Spline interpolations. I am not an expert on the theory there, but the maple help tells me that the first derivative of an 3rd degree spline interpolation should exist at the knots. But a derivation returns "undefined" at some of the knots instead. Here is my example:

x(t):=Spline([[0, 0], [1, 1], [2, 2], [3, 2.2], [4, 1.8]],t,degree=3);

returns

x(t):=piecewise(t < 1, .953571428571429*t+0.464285714285714e-1*t^3, t < 2, -0.9286e-1+1.09285714285714*t+.139285714285714*(t-1)^2-.232142857142857*(t-1)^3, t < 3, .65000+.675000000000000*t-.557142857142857*(t-2)^2+0.821428571428571e-1*(t-2)^3, 2.77857-.192857142857143*t-.310714285714286*(t-3)^2+.103571428571429*(t-3)^3);

diff(x(t),t);

returns

piecewise(t < 1., .953571+.139286*t^2, t = 1., Float(undefined), t < 2., .814286+.278571*t-.696429*(t-1.)^2, t = 2., Float(undefined), t <= 3., 2.90357-1.11429*t+.246429*(t-2.)^2, 3. < t, 1.67143-.621429*t+.310714*(t-3.)^2);

Not defined at t=1 and t=2. Is it possible to get an interpolation of which the first derivative exists at every point? Thank you very much!

This command (Student[Calculus1][ShowSolution](Int(e^(-(s-1)*t)))) shows me solutions.

and, the command in the picture can make integral solution but not laplace

so i ask you that what command make solutions for Laplace transform

y'(t)=1-y'(t-y(t)^2 /4),      t>=0

with initial function

y(t)=1+t,   0<=t<=1

please solve

guys 

in the worksheet i attached how can i collect  terms which include 1/w and 1/w^2 only ?

best regards

Sorry for making such a rude, big question. I have to solve these equations, but it's impossible ofcourse with my bad mathematics and even maple skills. Somebody help me pleaseㅠ_ㅠ
