I created two Maple animations in Maple 13 using the command "animate", which I then call with "display". The application works wonderfully. Now I am trying to create a Maplet around this program, and am having trouble finding any information or examples in the Help menu on how to create play buttons and whatever else is needed to successfully make this work. If you could give me some guidance or point me to an example somewhere that would be greatly appreciated.

hello could u help me with this error printf(cat(`$`(`%12.5 f`, 4)), `$`(vij(1, 1)[k], k = 1 .. 4)) Error, (in fprintf) unknown format code ` ` THANKS

r''-r(phi'^2+sin(phi)^2 theta'^2) -e^-r^2 = 0

Do you have any idea how to solve that ode?

I tried the following:

q:=(x)^(2)=a;
assume(0<x,0<a);
solve(q,x);
 

and received two solutions, though I assumed x and a to be positive.

Why? And what can I do, to make Maple account for my assumptions and only return the one possible solution?

I was doing a procedure for my programming class that classifies triangles.

I got the error "invalid terms in product"

I was wondering if anyone knew what that error means? I emailed my professor but he hasn't emailed me back.

 

Thanks,

Lex

Hello, everyone.

Here is a simple question.

How can I solve an equation containing a logarithmic function, for example:
eq:={40=53802.8616296/V-4421522.681759509154376431238971030890884/V^2-34696412.12593013477367899170424836286055/V^3-68770455564.45999796126160810938763183857/V^4+403332559275.4141930212434442368214769780/V^5+958128028485.0130104382506076504882209562/V^6-26140204752481.13476652750626233649550628/V^7+17375263330.60863159106251286006887257238*ln(V)/V^4,1258*0.9<V<1258*1.1}

 

I have a set of PDEs & I tried to solve it. First of all I defined some functions as:
H := (diff(a(t, y), t))/a(t, y), Hy := (diff(a(t, y), y))/a(t, y), H1 := diff(H(t, y), t), a1 := diff(a(t, y), t), a2 := diff(a1, t), Hy1 := diff(Hy(t, y), y), ay1 := diff(a(t, y), y), ay2 := diff(ay1, y), n1 := diff(n(t, y), t), n2 := diff(n1, t), ny1 := diff(n(t, y), y), ny2 := diff(ny1, y), pef := -2*n(t, y)^2*Hy1-3*n(t, y)^2*Hy^2-n(t, y)*ny2-2*n(t, y)*Hy*ny1-2*H(t, y)*n1/n(t, y), `ρef` := 3*n(t, y)^2*Hy1+6*n(t, y)^2*Hy^2, `ωef` := pef/`ρef`,

Hi,

i need to fourier transform 2D data to obtain spectrum.

I have 2 columns time ans intensity in that time. in another words i need to

FT(Y(X)), where X,Y are vectors.

 

i tried fft(2,x,y,) but theres no x(y)

 

can you please help me? I.m newbie in Maple and i need a fast solution:(

 

thank you

hello how to make integration of a a matrix????????

Hello All:

I have an if statement within a function. At some point, when the statement is evaluated I get an error message saying:

Error ...  cannot determine if this expression is true or false: 0. < 59.92088005+55.46829645*ln(.4804980261)

The right hand side is obviously greater than zero, but somehow maple does not seem to recognize this. Furthermore, this appears in the middle of a while do loop, and similar if statements are successfully evaluated with a true or false conclusion up until to this particular check point.

Need a sample maple code for a CSTR with heat exchange in unsteady state (for start up).

of a code which solves coupled nonlinear ODE's (stiff)

Thanks

How do I use the math tutor to plot on the same coordinate system? 

I am stuck on a problem with my homework.

It says to plot f(x)={2-x   -3(greater than or equal to) x (greater than) 1

                          e^x            x(greater than or less than)1

How do you plot them to show the e?

I am trying to solve a vibration problem with 40x40 and larger matrices. I am using "LinearAlgebra[Determinant]" function for creating the eigenvalues' equation. When the matrix is larger than 30x30 Maple gives an error "object too large". How can I avoid it?
