when I use s:=evalf(...), maple give me reasonable results but when I use s1:=evalf(...) for the same problem the results are different from previous case!

Can you help me, please?

I thought this was a really fun visual representation of the standard normal curve, although technically the standard normal curve extends infinitely in both directions.  Of course.... you can't evaluate a graph whose x-range extends from -infinity to +infinity.  (Although Maple does a great job of evaluating such integrals, assuming of course that the integral is convergent.)

If you have any suggestions, email me!

Thanks!

And happy holidays to the entire Maple community.

Hey guys,

I installed the 64 bit version of Maple 16, but it's still running as "maple.exe*32"? There is a similar quesion somewhere here...but this hasnt solved my issue...

There is no more Maple-software installed on the notebook. The other maple-tasks (mserver.exe) are running in 64bit-mode...

some specs: Thinkpad W520, i7-processor, 8GB RAM, Win7 (64bit)

Merry Christmas! :)

I'm very new user at Maple. i'm using Maple 13 and wrote a code taking help from another code. i'm writing my code here, i'm receiving error at highlighted line, also i'm unable to get any kind of out put.... plz d help

What about integrals along a curve and on the surface? How it may be presented by MAPLE tools?

I was trying to solve a VERY simple system of 2 equations,{ eq1,eq2}, for the variable d which appears only once to the first degree with coefficient 1. That is grade school algebra. Maple 15 refused; it needed help.

restart;
eq1:=s=a+b+c+d;
                    eq1 := s = a + b + c + d
eq2:=s=2*(a+b)*(a+c)*(b+c);
             ...

I have a list [1, 2, 3, 11, 29, 88, 252, 739, 2146, 6257, 18213, 53051, 154484, 449908, 1310217, 3815674, 11112091, 32360987, 94242573, 274456016]. How to select all even numbers of this list?
 

How to laplace transform for hypergeometric form in maple

if rsolve is solving difference equation for L(x) in summation(L*z^n, n=0..infinity)

can i use double encapsulation to solve for summation(L*z^n/n!, n=0..finity)

step 1 use rsolved result of a given classic difference equation times z^n/n! * t^n

step 2 then summation step 1 and use celine method to change into difference equation again

step 3 solve this new difference equation

then i imagine L should be L*z^n/n!

but i am not sure...

I have

f(x,y)=x y+x^2+1

and

g(t)=(2 t, 3 t).

I want to obtain the function (f o g)(t)  as a real-to-real one variable function.

What I tried:

f:=(x,y) -> x y+x^2+1,   it's ok;

g:=t -> <2 t, 3 t>,  it's ok.

But f@g  returns f@g.

How it would be possible to obtain f o g ?

I have an expression (with important physical meaning), I want to transform all the nasty numbers into scientific notations like transforming 203475439 to 2.0347e8.... anyone could help? thanks

:

2.03475439*10^8*(-1.*((203475439/5340588290000000000000000000)*n*Pi^2./V^1.+(1/2)*sqrt((41402254276242721/7130470820821281025000000000000000000000000000000000000)*n^2.*Pi^4./V^2.+(10681176580000000000000000000/610426317)*V+(1/2430046173368675201713890432319677067995801002565000000000000000000...

Hi,

I would like to know if the maple student version can give the analytic solutions of a system of non linear and/or linear equations. 

thanks

 Hi,

I have the following set of equations and boundary conditions. The problem is I cannot be able to make accurate guesses with the shooting method. I request your assistance. 

> k1 := diff(X[1](t), t) = X[2](t);
> k2 := diff(X[2](t), t) = M*(X[1](t)-1)-(2*(eta+b))*X[2](t);
> k3 := diff(X[3](t), t) = X[4](t);
> k4 := diff(X[4](t), t) = (2*Sc*Du*(eta+b)*X[6](t)-Du*lambda*X[5](t)-2*Pr*(eta+b)*X[4](t)-Pr*Ec*X[2](t)^2-Pr*Ec*M*(X[1](t)-1)^2)/(1-Du*Sr);

Hello everyone,

I have data in Excel sheet. I want to make the data smooth using cubic spline. 

My try can be found in the attached maple sheet. In my try, i was unable to see the

difference bewteen the exact data and the interpolated data. Please have a look and

help to smooth the given data in the attached Excel sheet.
