Hi,
I am trying to make the solutions for a class that I am the TA for using Maple in Document Mode. Is there a way to show the steps for Gaussian Elimination easily? (I know I could copy the intermediate matrices from the Tutor, but I am trying to avoid doing that.)
Thanks,
Laura

Last week I asked about manipulating a Matrix into the form:

pts := [[x1,y1],[x2,y2]...[xn,yn]]

I was directed to use the zip function, which after some trial and error I have "successfully" done. The problem I am having (I think) is that I am using Maple9. Using the zip function as in the example:

Hi,

I need to solve the heat diffusion equation in a system with two enclosed walls. The first wall (made of a material called **fr4**) goes from x=0 o x=d1, and the second wall (made of copper, that is **cu**)from x=d1 to x=d2.

**u(x,t)** is my unknown (change of temperature with time and space) for the first wall, and **v(x,t)** the unknown for the second wall.

So the system of PDEs to solve is:

>PDE:=[ diff(**u**(x,t),t) = afr4*diff(diff(**u**(x,t),t) **,**

Hi!

I have a function in 2 variables - lets make it easy, the function is:

f(beta,c_0) = beta-6*beta*c_0+3*beta*c_0^2

I want to know in which regions this function has positive values and where it is negative. Tried it with the command contourplot, but this is not telling me anything :(.

Hope somebody can help

Thx

Hello,

is there any way to solve a system like (d denotes the derivates):

f_{1}(x_{1},x_{2},y_{1},y_{2})=0

f_{2}(x_{1},x_{2},y_{1},y_{2})=0

dg_{1}(x_{1},x_{2},y_{1},y_{2})/dy_{1}=0

dg_{2}(x_{1},x_{2},y_{1},y_{2})/dy_{2}=0

Hi there, could someone help me plot zeta(0.5 + it) as seen here - en.wikipedia.org/wiki/File:Zeta_polar.svg

I assume I need to import some complex plot package?

This may have an annoyingly simple answer but I cannot seem to plot the prime counting function

This just gives me an empty plot. Any ideas?

I am very, very new to Maple and I know practically nothing. I have to create a number line, which I realize I use the plot command and x-axis, but that's about all I know. As an example, my professor gave "plot([[1,0],[5,0]],color=black,thickness=5);

Is it possible to export a Maple animation as a movie that can be inserted elsewhere like a PowerPoint presentation? I know that I can export a "still frame" from an animation but I would like to export the entire movie. Thanks. David
