u:=[x,y,z];v:=[a,b,x];
ListTools[MakeUnique]([u[],v[]]);

you could define a list of values to which the function is applied to:

L:=[10,20,30,40,50,55,60,65,70,75,80,85,90,95,100];
f:=(z)->(310*(z+0.5)^0.2)+70;
for i in L do f(i) end do;

sorry in case I misunderstood you

I'm not sure if this is the best way, but here some commands to make Maple's particular solution looking shorter.

restart;
with(DEtools);
f := diff(u[1](t), t, t)+u[1](t)+(3/4)*a^3*cos(beta+t)+(1/4)*a^3*cos(3*beta+3*t) = 0;
particularsol(f);
evalc(%):combine(%):simplify(%, size);

If you don't mind the % in your expression, you can use it to make your functions inert. The value command is the counterpart.

%cos(x+Pi);value(%);

Hi,

you should contact custservice@maplesoft.com

restart:
with(DynamicSystems);
sys := TransferFunction(1/(s+1));
NyquistPlot(sys, range = .1 .. 1.0, scaling = constrained);

Online Help page is more comprehensive than builtin help page:

solve(b^4-(2-d)*b^2-2*d*b+1+d > 0,b,parametric);

They won't review your student status at weekend, just relax.

Options:

restart:
y:= 2*x^2+7;
subs(x^2=freeze(x^2),y);plot(%);

Or in 2D Input Mode, select x^2 and press Cntrl+Shift+A to make it an atomic identifier

in four lines

S:=[0,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1];
for t in S do
t^2;
end do;

D[1,1,2](g)(x,y);
convert(%, diff);

f:=t->t^2;S:=[0,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1];

seq(f(t), t in S);

assign a value to x before executing your command variations, like x:=2; and see the difference

Hi Irene,
to overcome obstacles in an evaluation that decides a purchase, you definately should work closely with Maplesoft. Depending on where you live, contact your local sales rep, he will connect you to the tech support. If you don't know the contact, write a few lines to custservice@maplesoft.com. This is much better than this trial/error approach.

Don't forget to include your purchase code.
