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