Hi,

I am a new maple user and I am having a problem with this question:

 .

here is my maple procedure. I have to make the iteration works until I have met the initial condition it will stop. the initial conditions here is z:=ic.

This is my approach:

sum(1/(4*n+1/3*k),k=1..infinity)

but I end up getting infinity for my answer which is obviously wrong.

I am using Maple 13, I am working on Optimtimization package (worksheet mode) in command-line 

I am a student taking differential equations and I need to implement Euler's method using Maple 17. I have set up a do loop that looks like this:

for i from 1 to n1 do

k:= f(t,v):

v:= v + h*k:

t := t + h:

od:

Where n1 is initialized to 50, f(t,v) := 0.0207v² -893.58, and h is 0.1. v and t are both initialized as 0.

Hi ,,,,  I think it is a bug in Maple   "try to calculate int(abs(x-2),x);   ... does not give a right answer

Question 1

a := miu1 = Diff(lambda1(t),t) + lambda3(t);

b := miu2 = Diff(lambda2(t),t) + lambda1(t) - 4*lambda3(t);

c := miu3 = Diff(lambda3(t),t) + lambda2(t) - 3*lambda3(t);

d := miu = 2*Diff(lambda3(t),t$2) - 5*Diff(lambda3(t),t) + 7*lambda3(t);

how to eliminate all derivatives of lambda in miu

result in

miu - 2*Diff(miu3,t) - miu3 + 2*miu2 = 2*lambda1 - lambda2 + 2*lambda3;

I have now been stck in a few days on a task that should be done in maple. I'm pretty new to maple so hope some of you could help me a bit. The task is to create a table of a ball that is thrown, when the starting speed should be from 0.2 to 4, and each step should be at 0.2. Afther that the table need to be plotted. I have used euler method to sett the functions up and the functions is a vector. Any one know what comands i should be using?

I have here Maple proc, but it doesn't work. I am try to solve this equation 
pde := diff(u(t, x), t, t)-(diff(u(t, x), x, x))+x^2*u(t, x);

with 3 piont known , we have 
stencil:=u(i,j)=-u(i-1,j-1)+(1-h^2/8*v(h/2*(j-i-1))^2)*u(i,j-1)+(1-h^2/8*v(h/2*(j-i+1))^2)*u(i-1,j);

please see the file I attached here

Thank you

I am try to program a proc that will plot the kinematic equations.

kinematics := proc(a::procedure, t::name, s0::numeric, v0::numeric, t0::numeric, t1:: numeric)

local v:=t->v0+int(a(t),t);

local s:=t->s0+int(v(t),t);

plot([a(t),v(t),s(t)], t=t0..t1);

end proc;

the above is my code, which works ok. 

Note: a is acceleration function, v is velocity function, s is position function, t is independent variable,...

(i)develop an algorithm for computing f¡ÊF[x,y],F a field,where the degree of f in y is less than n and and f(x,ui)=vi; for i=0,1......,n-1, for distinct ui∈F,and arbitrary Vi∈F[x].showthat f is unique.

(ii) assuming that the degree of each Vi is less than m, what is the computing time of your algorithm (in term of m and n)?

(iii) computer f∈ F[11][x,y]such thatf(x,0)=x^2+7,f(x,1)=x^3+2*x+3,f(x,2)=x^3+5.

hello. how can I translate a graph in the x axis 3 times and then again in the y axis 2 times?
