Maple Questions and Posts

These are Posts and Questions associated with the product, Maple

for example:this equation:(1 - 2 x y[x]) y'[x] == x^2 + (y[x])^2 - 2

and how to make the solution in this form:

y=(x^3)/3+x*(-2+y^2)+C

not the form y=f(x)

 

 

 

sum((1/(1+2/a[k]))^(2*k+1)/(2*k+1), k = 0 .. n)

 

here a[k] >0, we may also assume that a[k+1] > a[k]

Hi! is there an option in Maple that can calculate a kernel and an image of a function. e.g. f: C -> R (complex to real numbers under addition) complex numbers expressed as w = x + i*y f(x + i*y) = x+y need to find ker(f) and im(f) - kernel and image of f. many thanx!

Hi,

Have a look at the following

+++++++++++++++++++++++++++++

test:=proc(s::string)
local M,a;
a:=rand(10..100)();
M:= Matrix([a-1,a,a+1]);
ExportMatrix(cat("Matrix_",s),M);
end proc;

+++++++++++++++++++++++++++++

test("1");test("2");test("3");test("4");test("5");test("6");

+++++++++++++++++++++++++++++

it saves in file

Matrix_1, Matrix_2,Matrix_3 .....Matrix_6

 

however,

I've got a block of code that I use once in a simple form, and then a second time in a more cascaded form but the second bunch doesn't work. And it seems as though tan won't evaluate numerically for me - it's really bugging me. Maple 11. Here's the block of code that does work: > eqn := Zin = (70.71*(100+(70.71*I)*tan(2*Pi*f/(3*10^8)*0.25e-1)))/(70.71+(100*I)*tan(2*Pi*f/(3*10^8)*0.25e-1)); > eqn1 := GAMMA[i] = (Zin-50)/(Zin+50); > eqn2 := (1+abs(GAMMA[i]))/(1-abs(GAMMA[i])); > sol := subs(eqn, eqn1); > sol1 := subs(sol, eqn2); > unapply(sol1, f);

Hi
I am facing problem with maple. I try to get a asymptotic series of a transcendental equation but I get failed again and again. If You people could help me.

I am waiting for ur kind responce.

Thanks

 

I was wondering how I double underline a result? E.g. 2 + 2 = 4 where I would like to double underline 4. /Ayatollah

 

how to orient the long label of the vertical axis "VERTICAL" ?

I am looking at some asymptotic expansions of a PDE and need to do some differentiating with complex conjugates.  Specifically, I have a number of functions that are functions of both z and conjugate(z), they may look something like:

 

S -> (z,conjugate(z),xi)

I would like to take the conjugate(z) derivative,

S[conjugate(z)]  = diff(S(z,conjugate(z),xi),conjugate(z)),

but I get:

D1S(z,conjugate(z),xi) + D2S(z,conjugate(z),xi)(-\frac{conjugate(z)}{z} - \frac{abs(1,z)}{signum(z)}

Hello people, Recently I recieved some help with binomial-solutions. I will most likely come with more questions while I'm working my way through my homework. In a bag there are 4 red marbles, 5 blue balls and 6 white balls. We select randomly and simultaneously 3 balls from the bag. What is the probability for each of the following events; a) The 3 balls have different colors. I did: binomial(4, 1)*binomial(5, 1)*binomial(6, 1)/binomial(15, 3) b) The 3 balls are all the same color. I did: (binomial(4, 3)+binomial(5, 3)+binomial(6, 3))/binomial(15, 3)

Hi i'm trying to code the jacobi method but my code dosen't work. Nothing happens. What hav i done wrong

Hi, I'm having a problem with the styles I set as default reverting to factory conditions after I close and reopen Maple. For instance, if i set the font to Calibri and make it my default Text font, it will revert back to Times New Roman when I open Maple again. Thanks

And in worksheet mode,or after click the Ctrl+J,ie insert Maple Input,

I can't use ctrl+=,that generate the results at the right hand.

Pic2 is the one after creating document block

How do I solve for the Lagrange multipliers of

f(x,y,z)= xyz +x^2 + y^3 +z^4

subject to the constraints:

g(x,y,z)= x^2 + y^2 + 2z^2=4

h(x,y,z) = 3yz + 2xz + xy =6

 

I've never used maple before so am completely lost and need to do this for an assignment=)

 

thanks

I'd like to start by thanking all those readers who left feedback on my last post. It was good hear that most of you enjoy reading my posts and that they are generally helpful. I would like to encourage you to continue posting feedback, especially questions or comments about anything that I fail to explain sufficiently.

The following is a discussion of the limitations of parallel programming in Maple. These are the issues that we are aware of and are hoping to fix in future releases.
