Question

blacksteel, tell me how you make those pretty matrices and vectors

Answer 1

Using the equation inserter.

The bottom menu has a button that looks like
(a b)
(c d)

If you press it, it will insert something that looks like this:\[\left[\begin{matrix}? & ? \\ ? & ?\end{matrix}\right]\]


You can then replace the question marks with whatever you want. And "& ?" to add another column and "\\ ?" to add another row. Play around with it a bit!

Answer 2

\[\left[\begin{matrix}4 & 6 \\ 1 & 3\\ 4 & 4 \\ oh you are brillant\end{matrix}\right]\]

Answer 3

that was easy lol

Answer 4

thanks

Answer 5

Haha, no problem.

Answer 6

(Also, you can delete "& ?" to turn them into 1xn matrices for writing vectors)

Answer 7

err, nx1 rather

Answer 8

\[\left(\begin{matrix}4 \\ 7 \\ 3 \\ 2 \end{matrix}\right)\]
cool!

Answer 9

\[(\frac{2}{3})^2\]
how do i make that exponent look more like an exponent
do you know?

Answer 10

\[(\frac{2}{3})^{^2}\]
i think i made the exponent smaller but not higher

Answer 11

unfortunately, i don't know. I usually just write \[(2/3)^2\]

Answer 12

this might be okay

Answer 13

joe say samething so i can give you a medal

\[\left(this\over that\right)^2\]

Answer 20

and this is for convenience :)

Answer 21

\[\left[ \begin{array}c 12 & 6 & -88\\65 & 8 & 1\\2 & -35 & 9\\-4 & 7 & 1\\ \end{array} \right]\]
