Hi, I need to maximize a quadratice function and I need to check if my variables are satisfying the Kuhn-Tucker conditions or not.

I defined the objective and I want to use the command

QPSolve(`ϕ`, assume = nonnegative, maximize);

and the Kuhn-Tucker conditions that I want to apply are

(&PartialD;)/(&PartialD; x[i]) `&varphi;`=0 and x[i]>=0; or (&PartialD;)/(&PartialD; x[i]) `&varphi;`<=0 and x[i]=0

I've tried all sorts of different assignments for a,b and c but all still give me an error 

for root 2. 

have tried posint, int, nonnegative, positve but none work 

any help would be appreciated. 

isTriangle:=proc(a::posint,b::posint,c::posint)
if (a+b) > c then print (a,b,c,`are lengths of a triangle`)
#this is according to the triangle inequality theorem
elif (a+b) < c then print ...

Dear All,

I found that the _Z is a already asked question from learners like me. However, I am asking for your inputs that are related to my problem.

I have a implicit expression interms of bessel functions. While making an attempt to solve (using solve command) for a variable , which is an argument inside the bessel function I came up with some output which has _Z as follows:

s,k,mu,sigma are parameters.k is real number

Trying to create slope field for du/dt=-u^5 + u^3 - u^2 + u but can't get an actual slope field to come up. Help? 

Hi! Just got help for my first question about Maple in here and it worked out great! :-)

I got one more question, I think it might be difficult to do, but let's see.

I've got a worksheet with about 6 equations. These equations depend on one single variable at the start (the first equation results in a value that the next equation uses and so on), the problem is, the variable has 11 different values, and I want 11 results that come out from...

I   have  the function W(Xi(t),ete(t),diff(xi(t),t),diff(eta(t),t)), a function of 4 variales.

I want to have all possibles second order partial derivative of this function with respect those variables

I have a procedure that outputs an array but I want to be able to see this on a plot, preferably a line. The 1s being on one side and the 2s being on the other side. Would this be possible? I have tried "with(ImageTools):" and then Creating an image then using the View command to view it but it gives me a solid square for an output.

Could anyone help to translate this (below) into Maple.  The Mathematica code understanding is causing me frustrations.  I got about as far as just starting to create the boggle board with the GraphTheory package. Here's what I have,which is rally barely anything at all. My example board 3x4
a := Graph(undirected, {["a", "b"], ["a", "e"], ["b", "c"], ["b", "e"], ["b", "f"], ["c", "f"], ["d", "a"], ["d", "b"], ["d", "e"...

Hi!

I just started using Maple for my engineering study some weeks ago, i have had luck finding help by google and forums so far. But now i ran into the first problem i can't find any answers for.

I want to add some values in a table like you can in excel. The values have to change like everything else in the document when then references changes and

Dear All,

I need help in adding following two set of equtions in MAPLE, your help will be really appreciated:

w:=2*Pi*100:  O:=5*w

S1:=100*cos(O*t)*(cos(theta)-(1/3)*cos(3*theta)+(1/5)*cos(5*theta)-(1/7)*cos(7*theta))

S2:=100*cos(O*t)*(cos(theta-Pi/6)-(1/3)*cos(3*theta-Pi/6)+(1/5)*cos(5*theta-Pi/6)-(1/7)*cos(7*theta-Pi/6))

S:=S1+S2

Also

Addition of following two equations required pls

X1:=100*cos(O*t)*(cos(theta...

I've found a fundamental difference in the use of 

G2:=CopyGraph(G):
and
G2:=G:

where G is a Graph in the GraphTheory package.

If I change G2 in the first case, G remains the same.

If I change G2 in the second case, G changes together with G2.

(The same happens when G is an input parameter in a procedure. Normally formal parameters cannot be changed, but if G is a graph there is no error message when changing G). 

What to do, to make maple evaluate the limit

limit(exp(-a*x), x = infinity)

where a>0 as zero? Thank you!

Just wondering if the Mma translator has improved much from M12?  Is it still being improved? 

With a myriad of ways to code something I can see how difficult it could be to try to code from one changing language to another changing language and try to decide which way is best to display.  Be it more efficient and less intuitive (making the smallest possible code is sometimes quite cryptic and difficult to translate), or more intuitive and less efficient. ...
