Hi,

please help me here:

I have a polynomial:

P := x->a*x^3 + b*x^2+c*x+d:

Now, first i want to find a, b, c and d. I know the following:-

1. value of P at x0 let it be e. 2. value of derivative of P at x0, let it be f. 3. value of P at x1, let it be g 4. value of derivative of P at x1, let it be h.

i used the following command:

solve({P(x0) = e, (D(P))(x0) = f, P(x1) = g, (D(P))(x1) = h}, {c, d, a, b})

but i am not getting any output****

now i want to solve P(x) = 0

Hello, I am new to maple 12 and am a bit lost. I am trying to do simple derivatives and it seems like maple is usually wrong when calculating even simple derivatives. I give it something like... cot(x/2) or even cot(x) and it gives me the wrong answer. Also, any quotient seems to be incorrect, a problem such as... d/dz[(z-1)/(z+1)] yields a incorrect solution. Is it just me? What am I missing? Thanks

Hi everybody,

 

Here's what I have:

 

First of all, is it possible for Maple to compile to create 'Maplet executable' so the use can execute the 'Maplet executable'  without Maple on the system?

 

If such is possible, how do I do it in Maple to create such Maplet executable on a working Maplet that I have created in Maple?

 

how do I open a Microsoft Access mdb file in Maple ??

Is present in last release of Maple an routine for the study of systems equation differential with delay?

Example, in my problem the DDEs:

y₁ (t) = y₅ (t-1) + y₃ (t-1)

y₂ (t) = y₁ (t-1) + y₂ (t-0.5)

y₃ (t) = y₃ (t-1) + y₁ (t-0.5)

y₄ (t) = y₅ (t-1) * y₄ (t-1)

y₅ (t) = y₁ (t-1)

<-Link#30 (Magnitude=IIvII=3, direction=u=<4,-4>=4i-4j)

<-#48(IIvII=3, u=3i+4j)

<-#64(magnitude=70lbs, 40lbs, 60lbs; @-30deg, 45deg, 135deg)

<-#74(velocity=580mph @ N60degW, wind=SW @ 60mph)

How does Maple  reduce that to unity? Thanks.

S := `assuming`([simplify(-sin(Pi*(alpha+n+beta))*sin(Pi*beta)/(sin(Pi*(alpha+beta))*sin(Pi*(-1+n+beta))), trig)], [`and`(`and`(alpha::real > 0, beta::real > 0), n::posint)])

I have to plot a graph where an equation C is dependent to two variables, and the equation changes depending on value of d.

I know plot3d(equation, range, range) gives you graph, but is there a way to plot a graph in only places where data sets are given instead of one smooth graph?

 

 

Below is something I tried to do which is not giving me results i want.

 

Hello,

I was trying to solve this nonlinear ODE using dsolve:

ode:=(diff(f,x)*diff(g,y)=1): dsolve(ode);

but got: Error, (in ODEtools/info) R equired a specification of the indeterminate function

 

I'm not sure what Maple means by "indeterminate function" .. does that mean I need an explicit function for g(y)??

I would assume that Maple would be able to do this without knowing g(y) since one solution is (1/n)*f(x) + n*g(y).

Thank you.

I have a 6*6 matrix which is A:[1,1,1,1,1,1],[1,0,-1,1,0,-1],[2,1,0,2,1,0],[4,1,2,0,4,1],[1,-2,1,-6,0,1],[5,4,-1,-2,5,0]

How can I show the system Ax=b is consistent or inconsistent if

x= [x1          b= [1

     x2                 0 

     x3                 1

Hi i was wondering if anyone could tell me what code i have to program the Bisection Method. I can't seem to get the while loop to work. it only gives me the first iteration and stops. Here is what i have done
 

 

f:=x ->x^3-x-8:
a:=2;
b:=3;
f(a);
f(b);

while sign(f(b)) <> sign(f(c)) do
if (f(b)*f(c)) > 0 then
b:=c:
else
a:=c;
c:=(a + b)/2
end if:
end do;
print(c);
2.5
 

I just can't get it to work.
 

I use Maple 9.5 on a Mac PowerPC G4.

Recently I have been unable to open a new worksheet. I have restarted my machine numerous times.

Do you have any suggestions for what to do--I am away from home and don't have the software to reload.

I think the problem first started because I opened some old files--running Maple 4 or 5.

 

Thanks,

Roger

 

Hello,everyone,

I have a problem with the symbolic equations,

would somebody help me to solve the follow equations, thank you very much!
