i have a problem in resolving this 5 equations eqn1 := (product(1-tau(i), i = 1 .. 4).delta.Delta.tau(0))*(1+(1/16)*(sum((16-j+1)/(g(0))(j), j = 1 .. 16))+(1-product(1-tau(i), i = 1 .. 4).delta.Delta).(1+(1/16)*(sum((16-j+1)/(g(0))(j), j = 1 .. 16)))+(1-product(1-tau(i), i = 1 .. 4).delta.Delta)^2.(1+(1/32)*(sum((32-j+1)/(g(0))(j), j = 1 .. 32)))+(1-product(1-tau(i), i = 1 .. 4).delta.Delta)^3.(1+(1/32)*(sum((32-j+1)/(g(0))(j), j = 1 .. 32)))+(1-product(1-tau(i), i = 1 .. 4...

I have Zipped 2 equations together to equate their equivalent Coefficients.  I now need to assign solve the list fot each value of N (1...9) How do I get Maple to do this reliably for the list as N 1..9 does not necessarily occour in sequence.

Hi,

I'm writting because I don't know how to solve this problem. I look for it in the web, but I don't

find the solution.

I have a vector with 4 variables, for example:

[54*a +3*b -c +d, 32*a -c +d, 96*b -69*c +85*d, 6*a + 9*b+3*c+9*d]

In really there is 4 equations. And I need to solve with other vector like:

[0,0,0,0]

I don't know the commands for do this... I search it in internet but I don't find anything.

u''-w^2+Eu^2=0,           u(0)=A,  u'(0)=0

How can I solve this question the variational iteration method with maple.please help me!

Hi,

I'm trying to have students solve a simple fraction problem like  $a - ($b + $c)  /   ($d - $e), where each letter is a programmed variable and where $d, $e and its difference do not give zero.  The answer could be either a fraction, or an integer (if the fraction can be simplified).  If I use the Maple-graded type of question, this is possible, but the student can also write the initial fraction problem and get a good mark for it ! ...

Hey Guys,

I'm trying to solve a system of 5 linear equations to get 5 unknowns:

Question :

Write a procedure that determines the solutions of a quadratic equation from inputs ,  and  by using the discriminant and the quadratic formula.

The quadratic equation procedure should be able to solve all cases: invalid input, linear case, real and complex roots. The procedure should also plot the given equation.

I dont understand how to do this can someone please please do it this for me urgently required.

I write this code:

> e1 := a-3;
                             a - 3
> e2 := sqrt(6)*b+6;
                           (1/2)      
                          6      b + 6
> trac := e1+e2;
                                 (1/2)  
                        a + 3 + 6      b
> dter := e1*e2;
                             / (1/2)      \
                     (a - 3) \6      b + 6/
> dell := trac^2-4*dter;
                           2                           

Hi I have a problem with the resolution of an equation. When I tried to solve it it returns "solutions may have been lost"... Here is the problem:

restart:with(Statistics):
> x:=rand()/10^12;

                               197859430267
                          x := ------------
                               500000000000

> X:=RandomVariable(Gamma(2,4));

                               X := _R

> XL:=RandomVariable(ChiSquare(3));

How to solve the  partial derivative at a specified point

The latex code is

f(x,y)=x+(y-1)\arcsin\sqrt{\frac{\,x}{y}}

f''_{xx}(x,1)

I have something like E1:=y=x*b+z*a+c*i. and i want to solve for y/i. I try doing solve(E1,y/i) but it says i cant solve for an expression. is there a way to get around that?

I've written 2 long nonlinear symbolic equations with 2 unknowns in Maple, but it doesn't solve it and says:"Kernel connection has been lost".

I have attached my worksheet to this message; what should I do?

would like to solve for x in terms of z from z in terms of x

however, x2 = RootOf(z2-z3-z1+_Z^3) , what is _Z ?

ex1 := {z1=x1, z2=x3-x2^3, z3=-x1+x3, z4=-x1+x4};
solve({z1=x1, z2=x3-x2^3, z3=-x1+x3, z4=-x1+x4},{x1,x2,x3,x4})

{x1 = z1, x2 = RootOf(z2-z3-z1+_Z^3), x3 = z3+z1, x4 = z4+z1}

how can i solve pdes of the following form in maple

[tex] tc(t,x)\frac{\partial a(t,x)}{\partial t} - ta(t,x)\frac{\partial c(t,x)}{\partial t} = a(t,x)c(t,x) + t(a(t,x))^2 and be able to find both functions a(t,x) and b(t,x)

Hey there,

how can i solve the following ODE in degree and not in radiant... numerical solution is required... im allways getting the wrong eigenfrequency.

>m*D(D(x))(t)+d*D(x)(t)+k*x(t)=sin(2*t)
