Hi I am getting a problem with plot. I am trying to plot ka (number of iterations) versus va (error norm) in this worksheet: > with(linalg):with(LinearAlgebra):with(plots):SOS:=proc(x) local n,k; n:=vecdim(x); sum(x[k]^2,k=1..n); end;NJ2Next:=proc(f,x,x0) local val,jac, xn, xn1, val1, val2; val:=eval(subs(x=x0,f)); jac:=eval(jacobian(f,x),x=x0):jac:=inverse(jac); xn:=evalm(x0-jac&*val); val1:=eval(subs(x=xn,f));xn1:=evalm(xn-jac&*val1); val2:=eval(subs(x=xn1,f)); evalm(xn1-jac&*val2); end: > NJ2:=proc(f,x,x0,N) local k, sol, valf, va, ka;sol:=array(0..N):sol[0]:=x0:va:=array(1..N):ka:=array(1..N):valf:=eval(subs(x=x0,f)): for k from 1 to N do sol[k]:=NJ2Next(f,x,sol[k-1]): valf:=eval(subs(x=sol[k-1],f)): va[k]:=evalm(log(norm(sol[k]-sol[k-1],2))):ka[k]:=eval(k):err:=evalm(norm(sol[k]-sol[k-1],2)): od: print(ka):print(va) :plot([ka,va]):end:

I need to find out how to input the code for the above question. I know that I need to enter B minus C but how do I find the complement of a set in Maple?

Hi, I'm trying for some time to create an adaptive procedure which modify the interval of the argument of a function depending on its values. The problem is that I still can't make the "if statement" to work the way I want it. The problem is that the cycle initiate some step "p" in the beginning and it use it trough the cycle although the value of the variable "p" already is different than the initial one. After printing it out, the interval changes with the initial value and the value of p changes independently. Which implies that Maple stores the initial value somewhere and use it from there, not from the immediate memory.

Hi, I noticed that in the lastest version of TexMacs 1.0.6.5 that maple is supported. I downloaded it. It appears to run OK, but I can't get the maple mode to load. It shows up in the session selection. I would appreciate any help or pointers. My system: Win XP fully updated and patch, Maple 10 or Maple 7 or Maple V.5. Thanks Ralph Wallace K9RWW@ARRL.NET

Jacob places $20 a week into an annuity to by a new boat. He receives 6% APR and saves for 10 years. How much money did he save up to spend on his new boat?

The two different investment offers: 6% compounded yearly, or 5.85% compounded weekly. Find the APR for each and determine which is a better investment.

There's initially 16 ants in the ant farm and 2 months later there were 24 ants. The box says the farm can hold a total of 1000 ants. Find the equation and determine when there will be 750 ants.

How do I find the dual of this? Thanks for your attention! F := evalDG(E1*dt &t dx + E2*dt &t dy + E3*dt &t dz - E1*dx &t dt - B3*dx &t dy + B2*dx &t dz - E2*dy &t dt + B3*dy &t dx - B1*dy &t dz - E3*dz &t dt - B2*dz &t dx - B1*dz &t dy Jim Bowmer.

Dear Maple community, I want to produce an animation of a double-napped cone and the plane for my worksheet. Have spent a few months attempting this to no avail (and lost the kernal once or twice). Can anyone help? Assistance is much appreciated. Thank you. Audrey Kirfoot

I have problem with this double integral int int (sqrt(1-x^2-y^2)) and x^6+y^6
