In 90's Maple was cool. Such things as fi, od, op, nops etc. were cool. They attracted many geeks.

LinearAlgebra:-LA_Main:-ReducedRowEchelonForm, end if, end do, and even ArrayNumElems  are not cool. That may be the reason, together with new Java interface (extremely not cool) why Maple stopped being cool in 2000's.

ok just trying to integrat something here

-[(tan(theta)) dtheta]/[sec(theta) (2cos(theta)-1)^(0.5) (1-cos(theta))] = (sqrt(Mgh/A)) t

and get to sec(theta) = 1 + sech (sqrt(Mgh/A)) t 

any advice?

Hello,

I have a simple acceleration/position problem that I can't figure out how to use piecewise to put into Maple --- can anyone assist?

Can we define dependencies of a variable after using the variable? For example, let us take,

f:=2*T+x^2;

Here, T has no dependencies. What should we do to make it dependent of x and y without redefining the whole thing as f:=2*T(x,y)+x^2;

and, can we do this for a whole matrix or vector?

Let us say that we have a code shown below:

restart:
with(DifferentialGeometry):
DGsetup([x,y],M):
e[1]:=A*ExteriorDerivative(x);
e[2]:=A*ExteriorDerivative(y);
simplify(e[1] &wedge e[1]+e[1] &wedge e[2]);

the output of this code is

How do I can generate eps figure from my maple calculation, in which expernal rectangular frame (solid lines) does not appear. I generate successfully the eps but I cannot remove the frame.

ok so i have the differnetial equation

[latex] \lambda^{2} (\frac{dx}{dt})^{2} = (cos{ \alpha} - x)(cos{ \beta} - x) [/latex]

where [latex] x = cos{ \theta} [/latex]

and the solution is

[latex] x = cos{ \alpha} sin^{2}{\frac{t}{2 \lambda}} + cos{ \beta} cos^{2}{\frac{t}{2 \lambda}} [/latex]

please show you're working cos that's where im getting lost

now i want to use maple to show this is the solution to the eqn.

how do i do this???

Hi to all,

I need to verify an multivariate equality in maple, here it goes:

Nr := 3 - cos(x - y) - cos( z - x) - cos(y - z);

Dr := (sin(x/2))^2 +  (sin(y/2))^2 + (sin(z/2))^2;

assume(x>0, x<Pi); assume(y>0,y<Pi); assume(z>0,z<Pi);

eqn := Nr/Dr;

I need to check whether eqn <= 6. I have tried

is(eqn > 6)  and is(eqn <=6) and both give FAIL as output. But if I change the denominator, Dr say Dr := Dr + 6;

Dear all:

hi!

I am trying to solve an ODE for w(x);

E - a parameter
MI - a parameter
w(x) - Transverse deflection
q(x) - Transverse force on the beam with respect to x
G - a parameter
A - a parameter
ap - a parameter
si - a parameter
mysol1 - differential equation to be solved with boundary conditions (bc1,bc2,bc3 and bc4) applied

Hi everybody,

I have a symbolic matrix (11x11) it is sparsely populated with components on the diagonal and 2 places either side.  When I have tried to calculate the [standar operations > nverse] (on a PC with Raid 0 and 4 Gb) Maple 12 stops running at 1883 Mb and complains about 'memory allocation?

Q1: how do I (inexperienced maple user) increase memory allocation?

Q2: when I tried to run a 5x5 matrix as a test a matrix wasn't returned, only a list of letters?

like (1+x)(1+2x)^2=(1+x)(1+4x+4x^2)

I think people can do that with Mathematica

How to make Maple simplify expression like

sqrt(  x^(2*a+2) )

to x^(a+1), where x is assumed positive?

The Maple's simplify works only if the constant 'a' is already assigned to a number, otherwise it refuses to simplify it, even if I tell it assume(x>0).
