\int_a^{\infty} f(x)dx=\lim_{L\to\infty}\int_a^{L}f(x)dx

[studiot]

Did you mean this - I have removed the opening  square brackets from the first math tag and the trailing one from the second.

math]\int_a^\infty  f (x)dx = \mathop {\lim }\limits_{L \to \infty } \int_a^L f (x)dx[/math

[math]\int_a^\infty  f (x)dx = \mathop {\lim }\limits_{L \to \infty } \int_a^L f (x)dx[/math]

I try with the "math" replaced by backslash square brackets:

\[ \int_a^\infty  f (x)dx = \mathop {\lim }\limits_{L \to \infty } \int_a^L f (x)dx \]

As expected the integral signs extend a little further.

[math]\int_a^\infty  f (x)dx = \mathop {\lim }\limits_{l \to \infty } \int_a^l f (x)dx[/math]

[math]\mathcal{F}_{x} [\sin(2\pi k_0 x)](k) = \int_{-\infty}^{\infty} e^{-2\pi ikx} \left( \frac{e^{2\pi ik_{0}x} - e^{-2\pi ik_{0}x}}{2i} \right)\, dx[/math]

 

got it for now....

I use an old version of MathType, which is a commercial program to generate the Math.

This allows me to type the maths in directly and copy / paste for the code in the webpage.

I see no reason to learn yet another language/convention but prefer to expect the machine to do the work for me.

Two free online alternatives are Sciweavers and Codecogs

I see reason. To become smarter..

I am always entering my LaTeX by hand using codes.

The more you're using it, the more comfortable you feel using it.

Both of these look good, not only for scienceforums. I don't use latex much on this forum, which is why it always seems like a major task to get [math] or \( etc right. Like almost everyone who didn't write the software, I feel the recent 'upgrade' was in effect a downgrade.

I use gummi  a fast wysiwyg latex editor on my computer. Not windows friendly, but can be easily installed on e.g. most linux Ubuntu OS using Synaptic Package Manager.

(I use Linux Mint.)

I see the programming industry as being in the same stage and displaying the same arrogance towards customers as Henry Ford with his  "Any colour so long as it's black" comment.

Growth and competition has yet to force them to actually find out what customers really want.

That really depends on size of company... Corporations ("conglomerates", "city in the city", "state in the state") are reluctant to listen customers. Try to send e-mail or contact anybody in such "worldwide leader" IT company (I will refrain from mentioning names). Good luck. It's hard/impossible even to find such option on their websites. There is "contact" which opens page with FAQ, frequently asked questions, and you enter question to them, and algorithm is trying to search answer.. if it's not found, you're screwed.. I always have unusual uncommon nonstandard requests or suggestions.. and it's practically impossible to contact programmer and tell them "do this or that".. There is "wall of layman" at the lowest level of queue between customer->support (layman IT) -> management -> programmers.

Small companies almost always have properly working contact pages or even direct e-mails to everybody in the team. So it's possible to write them suggestions which really will be implemented.

That's growth caused them to start behaving like this. Imagine you have millions of customers and the all yours programmers in the team is dealing the all day long with thousands of users who request assistance etc. etc. They would be unable to work on their products in such environment. Not even mentioning HR from competitors who are trying to enlist..

Test of Mathpix Snipping Tool...

Select a partial screenshot, paste from clipboard....

From my last post here

S=N k\left(\ln \left(\frac{V_{x}}{N}\left(\frac{4 \pi m U}{3 N h^{2}}\right)^{\frac{3}{2}}\right)+\frac{5}{2}\right) ie.

[math]S=N k\left(\ln \left(\frac{V_{x}}{N}\left(\frac{4 \pi m U}{3 N h^{2}}\right)^{\frac{3}{2}}\right)+\frac{5}{2}\right)[/math]

 

From this image at   https://www.scienceforums.net/topic/117535-probability-interpretation/

 

 

 

[math]\begin{array}{l}{P_{1}\left(E_{1}\right)=\left|\left\langle\phi_{1} | \psi\right\rangle\right|^{2}=\frac{3}{5}} \\ {P_{3}\left(E_{3}\right)=\left|\left\langle\phi_{1} | \psi\right\rangle\right|^{2}=\frac{3}{10}}\end{array}[/math] and

[math]\begin{array}{l}{\text { Why not }} \\ {P_{1}\left(E_{1}\right)=\left|\left\langle\phi_{1} | \phi_{1}\right\rangle\right|^{2}=?}\end{array}[/math]

Pretty good for free software...
