Hello to everyone

Pls help,urgent....

I need to draw the deformation of one story building (for simplicity, 4 columns and 2 floors) whose columns and floors  under influence of external load acting to the left of the building at its intersection point undergo the deform shape like S . So means that when the building moves to the right its intersection point of column and floor has some small rotation.

I am new to Maple environment...

how can i solve pdes of the following form in maple

[tex] tc(t,x)\frac{\partial a(t,x)}{\partial t} - ta(t,x)\frac{\partial c(t,x)}{\partial t} = a(t,x)c(t,x) + t(a(t,x))^2 and be able to find both functions a(t,x) and b(t,x)

I want to solve numerically the nonlinear problem 

a*(diff(y(x), x, x))+2*(diff(y(x), x))+exp(y(x)) = 0, y(0) = 0, y(1) = 0

by defining my own method defined as 

y_n+1=y_n+2*h*(-2*y_n+2*ln(2/(1+x))-(1/2)*a)^2/(a*(-4*y_n+4*ln(2/(1+x))-a-h*(4*y_n-4*ln(2/(1+x))+a+x+1)/a))

where h is the step-size. Please help me by letting me know how can I do this using Maple 11.

Can someone tell me how Maple coding written in worksheet mode can be fully transferred into a Word document taking all maple's commands, alignments and any section's arrows as they apper in worksheet mode? 

I found that after using "Export as" (tried everthing there), my worksheet appers to be abrupt, alignment of certain codings changed and all the arrows of sections removed.

Please tell me how to deal with this issue, I need to transfer my maple coding...

HI,

I measured some points. This points are plotted in a graph. Now I want to make a fit on this points.

I now that the fit-function has to be like this:

F = A + B1 x e^(-t/C1) + B2 x e^(-t/C2)

Problem: how can I create a fitting function like that?

The best thing I found is the "spline"-fit, but it doesn't work properly. It has to be one lonely function, not a summary of several functions (like spline).

How can several expression statements be not displayed during and after an execution process of "then"conditional statement (I mean "If.....then...")?
For example:

if .... then
exp1:
exp2:
exp2:
....... 

end if;

each expression above can consist of various commands in its body.All my exp statements were finished by ":"
but, they...

for example, how to define f(x,y)=sin(x+y) inside a triangle but f(x,y)=0 elsewhere? 

A simple question. I have this:

k*(2x+y-3z+2)+s*(5x+5y-4z+3)=0

And I want to group it by x, y, z, so that I would get:

x*(2k+5s)+y(k+5s)...=0

I'm using Maple 11.

Does anyone know how to create one in maple? please see the example attached..

Hi there,

I am designing a Buck Converter Power Supply, and in that regard I need to design the input filter and compare it to the characteristics of the converter, and for that I need to compare two Bodeplots.

How can I plot the two Bodeplots that I have attached in one?

Thank you

I put Celsius in my equation and I get the wrong answer even though I've loaded the Units Package:

I have to put in the conversion to Kelvin by myself to get the right answer:

What am I doing wrong?

Thanks ahead of time!

hi, i am a danish htx student and we use maple for our math lessons, when i started here i installed maple 13 and it has been working fine, but our serial runs out so i had to upgrade to maple 15. when i did i uninstalled the previous maple version and installed the 64 bit maple for my 64 bit windows vista. now when i try to do for instance f(x), the ( and ) breaks maple and all text/numbers vanishes, if i open my previous school homework they look empty aswell. clicking and...

Hi! I need some help with a curve I'm trying to plot.

I'm asked to intersect the surface produced by f(x,y) with the plane z=1/4 and to plot the curve generated by the intersection (in 3D). I found how the curve looks like but I don´t know how to plot that in 3D.

Hi!

How I can pass value directly from slider to expresion without executing whole worksheet?

I need to create an ellipse and an ellipsoid (ellipse in 3D) through code. How would I be able to do this? Can someone please give me an example for each?

Also, I will need to create a line for an ellipse and a plane for an ellipsoid that intersect. Would I be able to find the intersecting points? Would I be able to find the function for the curve line that is created when a plane intersects an ellipsoid? Also, how would I find the surface area and volume...
