I'm a physics undergrad at concordia. I started last fall after finishing a degree in computer eng. in lebanon. I wanted to go to mcgill, and i got refused too (i only had 3.1-3.2 gpa since i wasn't that interested in eng.). The physics program here (so far) is satisfactory to me. There are some...
Thanks robert Ihnot for this explanation. I guess this is the first time i get exposed to ancient mathematics. I hope i can get the time to fiddle with them before my finals. I'll also try to contact my prof soon and see if his paper about them was published or not.
The page that provided states that the conjecture is solved? (however, i still don't fully understand the conjecture yet). Anyways I'm still curious...
One of my former teachers claimed that he had solved an ancient problem (4k y/o) called Egyptian 2/n-table. He told me (a while ago) that he submitted his proof to historia mathematica but i didn't communicate with him since and didn't know what happened next. I'm wondering if anyone could show...
Thanks HallsofIvy. I already solved it, and it was easy as expected (i just didn't know the mathematical interpretation of the word 'insulated' in that context).
yes, i made those horrible typos sorry again (been up very early having nothing to do but solve). I will try solving it, i think it should be easy. Thanks for the input.
I'm sorry, I (falsely) assumed everyone would recognize the equation i had in mind. The equation is
\frac{\partial^2 u}{\partial t} = a^2 \frac{\partial^2 u}{\partial x^2}
With U(0,t)=0. U(L,t)= ??
I know how to solve a 1-D heat conduction equation when both ends are kept at 0 temperature(using separation of variables and Fourier series.). In the notes, the prof asked us to solve for one end kept at zero and the other insulated (at x=L) and referred to a non-existent chapter in our...
Maybe if it's hard for you to integrate 1/(1-ax) with respect to x then you do have a problem?
Taken from 1/a onwards, the integral of 1/1-ax is (-1/a) ln |1-ax|. Knowing how that solve your problem without needing the calculator.
Hi. I've been trying to find some material about Fourier Series in 2-D, along with 2-D Orthogonal Systems, but i haven't been able to find any about the former in any of the books i have (Toslov and Butkov's Mathematical Physics) nor online (nothing on mathworld?). Any input would be appreciated.
I've always seen Mathematics as the study of mathematical relations among different abstract ideas (i know the defenition is a bit recursive). Most of the time i find it difficult to understand those abstract ideas but get familiazed with the relations among them faster. However, knowing the...
Thank you HallsofIvy for clarifying this matter. This must be the reason why the other methods for finding the residue are not applicable, just like what Deadwolfe suggested. That explains a lot. And thanks for the rest for your input.
