What does "same dimension" mean here?
Would the group of matrices (A_i) have the same dimension as the group of Matrices \left ( \begin{array}{*{2}{c}}
A_i & 0 \\
0 & 0
\end{array} \right) ?
You forgot the squareroot and the limits, but the rest looks fine. You just have to calculate
L = \int \limits_a^b | r'(t) |\mathrm{d} t = \int \limits_0^1 \sqrt{1^2 + (\sqrt{2}t)^2 + (t^2)^2 } \mathrm{d} t
I don't know if I got the question right (had linear algebra a long time ago). Can we assume \phi(\lambda_1 w_1 + \lambda_2 w_2) = \lambda_1 \phi(w_1) + \lambda_2 \phi(w_2) and that there is a basis for G_1, G_2 ?
I think it works something like this then:
If { (a_1, a_2, \dots , a_n)...
Hi,
I got an exam in calculus in a few weeks, and lots of questions coming up. Here's one of them:
We learned that the Fourier Transform of
f(x) = e^{-|x|}
is
\hat f(\omega) = \sqrt{\frac{2}{\pi}}\frac{1}{1+\omega^2}
I've got no problem with this one. Now, since \hat f(\omega)...
As far as I know there are such programs for my Linuxbox, too. But I just want to get latex-equations displayed by a regular mail program, without opening a gif/pdf. Of course, the mail software may use the "equation service" or alike to create gifs and display them in the text, but it should do...
I guess you could, but lots of people don't like HTML-mails. It wouldn't be very nice to use either.
What I'm looking for is a solution which makes up the formulas from the tex-code, just like the software in this forum does, everytime it sees a [tex]-tag. A plugin for Mozilla Thunderbird would...
Hi,
I wonder if there is a proper way of discussing physics and maths in email. Of course, you can just use the LaTeX code, and mostly everybody will understand it. But wouldn't it be nicer if you got real formulas displayed in your Email-prog instead? But until now I found no email-program...
