Download failed? Too big? Try Firefox

I tried downloading a huge Bb export the other day (4GB) and it failed 4 times in Chrome. Jamie tried it in Firefox and it worked!

However the biggest upload you're allowed to do is 2.5 GB, so I'm moving big files before the download next time.

È French keyboard

Sometimes you in inadvertently change your keyboard into a French keyboard by holding down Ctrl and Shift at the same time.

Fortunately, you can get back to an English keyboard the same way.

How to get = to align in LaTeX

There may be instances where a few lines of equations look bad because their equal signs are not aligned, like this one:


The way to do it is to start by declaring you are starting LaTeX:

[latex]

Then tell it you are using \begin{align}

[latex]
\begin{align}

Then put in the first line of LaTeX code with an & where you want to align it, so in our case, before the = sign:

[latex]
\begin{align}
y &= 3(x)^4(2x -5)

At the end of the line, put a space backslash backslash ( \\). This makes a line break.


[latex]
\begin{align}
y &= 3(x)^4(2x -5) \\

Then you might want an empty line to separate the next line more, put another space backslash backslash ( \\).

[latex]
\begin{align}
y &= 3(x)^4(2x -5) \\
 \\

Put in the next lines of math similarly, remembering the & before the =.

[latex]
\begin{align}
y &= 3(x)^4(2x -5)\\
\\
\dfrac {\delta y}{\delta x}&=3x^4(2)+(2x-5)12x^3 \\
\\
&=6x^4+24x^4-60x^3 \\
\\
&=30x^4-60x^3 \\

At the end, close alignment with \end{align} and close LaTeX with [/latex]

[latex]
\begin{align}
y &= 3(x)^4(2x -5)\\
\\
\dfrac {\delta y}{\delta x}&=3x^4(2)+(2x-5)12x^3 \\
\\
&=6x^4+24x^4-60x^3 \\
\\
&=30x^4-60x^3 \\
\end{align}
[/latex]

The finished product will look like this:

Trick WordPress into accepting a minus sign

MS Word has a few different symbols that look like a minus, and only one is acceptable in Word Press





So once in Word Press, delete whatever looks like a minus, and retype a minus in it's place

\small to fit regular font size

Maybe LaTeX is made in Texas (if so I won't "mess" with them), but their regular size is a bit big.

To compensate, put a \small infront:
