hello everybody

I need help please


in some forum i found this problem

find a number "abcdefghijklmnopqrstuvwxyzâôîé" with 30 digits if we renverse it

it will be equal 

(éîôâzyxwvutsrqponmlkjihgfedcba)/4

hello everybody

please heeeelp

hello everybody can you help me please

 

how can i canvert this list [1,2,3,4,5,6] to a number 123456

 

Dear all,

I am running Maple 11 on my PC. I have Windows 7 (64 bit installed), use Eclipse SDK for Java development.

I have made some mathematical calculations in Maple 11, now I want to integrate them to Java using OpenMaple API.

I viewed help, maple soft and maple primes resources ...... I found test.java example in Maple 11 directory.

 

I can't add classpath to OpenMaple libraries in Java.

I have Java SDK 6 installed in...

hello everybody

i want to know how can i solve this equation

64(a-b+c+d+e+f+g)=32(b-a-c-d-e-f-g)=16(7c- a-b-d-e-f-g)=8(15d-a-b-c-e-f-g)=4(31e-a-b-c-d-f-g)=2(63f-a-b-c-d-e-g)=127g-a-b-c-d-e-f

 

please heeelp me

Hello

i want to solve this equation

but i couldn't

please help me

 

( x mod 5656 = 565 ; x mod 565 = 56)

I setup Maple 11 on windows 7   but the program does not save any data

Dears, How can i plot a parametric equations for an ellipse

x[i]=a*sin(t[i]),     y[i]=b*cos(t[i])      t[i] takes a numerical vaulues from - Pi to Pi.

i.e

i want to plot the values ,

(x[1], y[1]),

(x[2], y[2]),

.

.

(x[i], y[i])      where     i=1..100,

Dears. I want to evaluate the following expression numerically
G[i]=sum(Gama[i,k], k=1..100, k<>i),
where
Gama=((x[k]-x[i])*xdot[k]+(y[k]-y[i])*ydot[k])*dtheta[i]/((x[k]-x[i])^2+(y[k]-y[i])^2)^2

  Dear all, I am using fsolve to solve a complex equation. When I solve it, I get the following error:

Error number of equations, 1, does not match number of variables, 2.

But the variables are just one (named u1) I think it is a problem with assume but I am getting cracy to understand the problem.You can find in attachment the short maple file. I try to solve equation e4 for variable u1.

thanks
Alberto

Recently, I submitted for publication to a peer-reviewed math journal

a formula for the n-th order implicit derivative given an implicit function G(z,w)=0.

i.e. dz/dw = - Gw/Gz where Gw and Gz are partial derivatives of G with respect to w and z, respectively. Anyway, I proved the general formula for d^n z/ dw^n.   I have since proved the generalization of this to implicit functions of several variables, G(z,w1,w2,...,w(N))=0. A good mathematician...

Hi, 

How can I create a matrix M by M with maple, where the elements of diagonal comes from b[i]=i+1 and the other elements comes from c[i,k]=i+k.

Hi

I want to find the optimum of

G*(.7500000000*B*sqrt((1.-2.*a+a^2)*B^2/(a^2+B^2-2.*B^2*a+B^2*a^2))-.7500000000*B*sqrt((1.-2.*a+a^2)*B^2/(a^2+B^2-2.*B^2*a+B^2*a^2))*a+.7500000000*a*sqrt(a^2/(a^2+B^2-2.*B^2*a+B^2*a^2)))

+

(1-G)*(-6.250000000*10^(-12)*sqrt(a^2/(a^2+B^2-2.*B^2*a+B^2*a^2))*(5.833333333*10^9*B*sqrt((1.-2.*a+a^2)*B^2/(a^2+B^2-2.*B^2*a+B^2*a^2))-7.500000000*10^9)*(4.*a-3.*B*sqrt((1.-2.*a+a^2)*B^2/(a^2+B^2-2.*B^2*a+B^2*a^2))+3.*B*sqrt((1.-2.*a+a^2...

hello all, I'm trying to solve ODE's but my computer takes a very long time evaluationg. and still not giving an answer for more than 4 hours.

so please is there anything error in my solution

deqs := {NULL
         , diff(u2(y), y, y)-((h^2/K)+m*h^2*M^2)*u2(y)+m*b*rho*h^2*GR*(c3*y+c4) = 0
         , diff(u1(y), y, y)-((1/(K*(1+k1)))+(M^2/(1+k1)))*u1(y)+k1*(diff(N(y), y))/(1+k1)+GR*(c1*y+c2)/(1+k1) = 0
