hey !
Thanks guys for looking at my work.
I can't see how the indices don't add up... maybe i am missing something... but
Each component of
\[
\mathbf{P}\] will be a function of the \mathbf{\mathrm{D}^{-1}} tensor.
about division by the tensor..
x=\mathbf{D}y for some 'x'...
Could someone help me out ??
I tried this integration over the surface of a sphere of unit radii,
\[
P_{mn}e_{m}\otimes e_{n}=\frac{1}{D_{pq}e_{p}\otimes e_{q}}\int e_{m}\otimes e_{n}dS_{r=1}\]
and I always get \[
4\pi e_{m}\otimes e_{n}\] and the 'D' tensor as it is..
I am...
Someone please nominate me for the Physics Nobel Next year... I have lots of vision, I 'hope' to unify all the theories consistently. I am highly motivated tooo , all i think about is physics everyday... if possible my friend (he works in McDonalds) tooo, he is a visionary, highly motivated by...
Hi,
I am trying to guess the solution for this i am sure the solution involves a ln(x) so that i can reduce the order to find the general solution but i just can't seem to find it... any suggestions ??
\[
(c_{o}+xk)y''+ky'=0\]
with ths usual boundary conditions...
hey,
I Just got it,
I used this substitution.
\[
\intop_{0}^{\pi}\intop_{0}^{2\pi}f(cos\varphi sin\theta,sin\varphi sin\theta,cos\theta)sin\theta d\theta d\varphi\]
the radius that i used in the variable substitution is not the same as the unit radius.
Homework Statement
\[
\underset{\left|\underline{\xi}\right|=1}{\int}\delta_{0}\left(\underline{\xi}\cdot\underline{z}\right)dS_{\xi}=\intop_{0}^{2\pi}d\varphi\intop_{-r}^{+r}\delta_{0}\left(\varsigma\right)\frac{d\varsigma}{r}=\frac{2\pi}{r}\]
The \delta_{0} is the dirac delta function.the...
Hi,
I am not really sure whether its over the surface of the sphere or the Volume,
the problem and the solution are given below, I want to know how it has been solved.
The \delta_{0} is the dirac delta function.
\[...
Is this Right ?
\[
=-\frac{1}{2}\left(\underset{k}{\sum}\left[n_{k}+\theta n_{j}^{\star}\right]z_{k}^{2}\right)^{-\frac{3}{2}}n_{j}^{\star}\nabla\underset{k}{\sum}\left[n_{k}+\theta n_{j}^{\star}\right]z_{k}^{2}\]
\[
+\frac{1}{2}\underset{k}{\sum}\left[n_{k}+\theta...
I was working on some of my own equations and today i ended up with this differentiation thinghy, I never expected this in my equation but it just turned up :( so if there's anybody out there who loves to solve math please give this a try :)
maybe its too simple :) ... i am just having doubts...
I am good in Mathematics, the more the abstract the better, but when it comes to phsyical situations or physical problems in Engineering with simple formulae then there's a problem :(
I have really spent a lot thinking about it, i still do like the Engineering way and also the Mathematical...
I agree with you, I actually want to find out what am I good in,
Am I a Mathematician without an undergrad Math degree or an Engineer who has to work much harder and find out if i still have the aptitude ...
Do u have any suggestions which can help me decide ??
I however am not planning...
well, i find it quite difficult to visualize stuff like mal4mac says,do you still think i can make a good engineer ? coz me having plans to do start my Ph.D in a few months.
One more question, I thought probably i will finish My PhD and then get into the industry, anybody here who has done...
hi,
Thanks a lot for your suggestions :),
The reason I wanted to read those books were because there are 2 guys in my class who have completed their bachelors degree in Mathematics(Hons.) and often they start talking about Topology, Hilbert spaces blah blah during the finite element...
