I right click my units and it does not give units to simplify

A new edition of The Mathematics Survival Kit – Maple Edition is now available.  It contains 25 new topics, which were created in response to requests from readers of the first edition of the book. New materials range from basic operations such as factoring and fractions, to graph sketching, vectors, and integration.

The Math Survival Kit gives students the opportunity to review exactly the concept or technique they are stuck on, learn what they need to know,...

I use Maple in high school. My students deliver their homework created in Maple. Often this involves solving a number of exercises, say 7. Not all students are completely aware of how the Maple Engine works, so I tell them to put in restarts from time to time, at least when a new exercise begins. This prevents misunderstandings and loss of time which might else happen when calculations in one exercise interferes with calculations in the next exercise. One simple example...

I am gettinga string from a textfield

In my program that String represent a set of 8 bits

ie. g(t)= 10101110

But I need to separate them like

n0=1

n1=0

n2=1

...

n7=0

where each n is an integer

how do I do it?

Hi,

I'm trying to use a simple DLL in maple, which I create based on Maple external linking examples..

int __stdcall mult( int a, int b )
    {
         return a * b;
    }

and I compiled it with Visual Studio 2010 compiler, but when I use it in Maple I recieve the error

"Error, external linking: error loading external library"

thanks

Hi, I'm trying to use rsolve to solve the difference equaiton: y(n)-3*y(n-1)-4*y(n-2)=delta(n)+2*delta(n-1)  where deta(n) is the discrete delta function represented by charfcn[0](n).  The answer should be y(n)=(-1/5)*(-1)^n+(6/5)*4^n.  I'm getting the answer in terms of y(0) and y(1) and extra terms.  Can someone point me in the right direction?

Thanks for your help

i got a set of roots of nonlinear equation by fslove method.e.g.

y1:=a^4+b-3=0;

y2:=a^3+b^2+2=0;

fsolve({y1, y2})

⇒{a = -1.402752934, b = -.8719054433}

i got roots value of the equation,but i want to continue to use direcly the float values of 'a' and 'b' in my program,but i couldnt ues them by some methods since 'a' and 'b' didnt seem to be assigned.so i had to write the values in a text file,then...

Hi,

i have system of two equastion with two vairable (x,y) and paramater ( b1,...,b4, a,...,a4 ) as follow,

 q:=b4*(y^3)+b1*x*(y^2)+b2*(x^2)*(y)+b3*(x^3);

q1:=a*y+a1*x+a2*x*y+a3*(x^2)+a4*(y^2);

solve({q,q1},{x,y}):

maple doesnot  give any result except o,o solution

can you help me to solve this problem ?

is there any package that able to find the solution reither than numerical method?

Hi,

i have a same problem , could you please help to solve this problem?

I used maple help to solve my problem but for this one I could not.

I have equation system with 4 equations and variables are for example x y z w .

The problem is I  have  xy  x^2  x^3  yw   in my equations so maple with solve could not solve that.

On the other hand,the equation are parametric and non numeric I mean the answer...

I get a data of string type from .txt file,but i want to use the data from string type to float tpye in my program,In fact ,i had tried in many methods,convert,sscanf,type etc.but, i coundnt solve this problem until now.if u know,please tell me how can i do.

example:

x:="0.01"⇒x=0.01

Hi, can someone tell me how to approach converting an expression is z to one in powers of z^-1?

For example, express f(z) = z/(z-1) as 1/(1-z^-1) ?

Thanks

I am trying to determine whether there is a particular order to how Maple displays complex and real solutions to equations. for example if I input

>solve(diff(x^6,x)=k,x);

There are obviously complex and real solutions to this, and the output displays both but does Maple always display the real solutions first?

Thanks.

Hi,

I try to find minimum value for numbers as follow,

for i from 1 to 1000 do

x:= 1+i; 

y[i]:= 2*x+1;

a:=min(seq(y[k],k=1..1000));  print(a); od;

in this case the maple can not provide any solution

however, when i use 100 instead 1000 i obtain result as follow,

for i from 1 to 100 do x:= 1+i;  y[i]:= 2*x+1; a:=min(seq(y[i],i=1..100));  print(a); od;

could you please help me to solve this problem?

Hello,

I am currently trying to build some procedures in Maple that calculate the Legendre-Fenchel transformation for functions that are convex, nonconvex, differentiable and non-differentiable functions. I seem to be ok in the convex case, but cannot seem to find a way of getting Maple to calculate this transformation symbolically for nonconvex functions (both differentiable and non-differentiable). It appears to me that the only way to deal with these cases is to...

Hi

My Maple 13 puts small curly brackets to the left side of an expression and this causes several problem for me. What should I change to write good ones? (I mean normal, big brackets, not small brackets to index.) (I use the AltGr+b combination to write a left curly bracket.)
