Question

I have a huge problem with my course "Mathematical methods for physicists"

Need to solve a problem (in Mathematica for starters), but don't even know, where to begin.

Maybe someone could help me out a bit?

The problem explained in next post:

Answer 1

okay

Answer 2

\[\delta(u)/\delta(t) = a^2*\Delta u + \gamma u + f(M,t)\]
\[M=(x,y,z)\]\[x \in R , y \in R , 0<z<H\]\[t >0 , \gamma \ge 0\]
Boundry conditions :
\[u (t=0) = 0 ; u(z=0)=A ; \delta u / \delta z (z=H) = 0\]\[A \in R\]

- Give phyisical interpretation (from what i understand, its thermal conduction equation)
- find \[v=\lim_{t \rightarrow +\infty} u(M,t) if f=f_0=const\]
- What is v if a-> + infinity


---

in first line delta before u is Laplacian

functions u and v are some temperatures i guess, where v is temperature on boundary.

Answer 3

correction in first line :
\[\delta(u)/\delta(t) = a^2*\Delta u - \gamma u + f(M,t)\]

Answer 4

O.o

Answer 5

EXACTLY! XD

Answer 6

im only in algebra one so no way im soving this! Good luck

Answer 7

Can anyone help me with why the graph isn't plotting???

I'm confused, because everything seems fine to me.

Answer 8

I would google the subject then mathematica thats what I've done for everything I've done on mathematica they have really awesome guides

Answer 9

mathematica it*
