Hello, world!

Go home.

What about “quotes” you say? I don’t know–maybe not–can we find out… Like ‘quotes’ or just “quotes?”

So $\begin{bmatrix}0 \\ 2\end{bmatrix}, \begin{bmatrix}1 \\ 7\end{bmatrix}, \begin{bmatrix}2 \\ 12\end{bmatrix}$
, and any other points on that line, are all *possible solutions to this matrix equation*.

- If we set the current to any other value $x$
, the voltage across the two terminals will be along the straight line connecting those two points on the V-I plane: $$\begin{align} V_{A B} (i=x) & = \text{OCV} \big( 1 - \frac {1} {\text{SCC}} x\big) \\ V_{A B} (i=x) & = \text{OCV} - \frac {\text{OCV}} {\text{SCC}} x \end{align}$$

Or on its own:

How about inline equations? $2+2=4$ Yeah, that works. With underscores? $x_b=y_a$ And more? $V_{\text{A}} = \big( x \big) _A \cdot j_ A$

Inline accidental html? $x<b>y$ but this should NOT be bold $5</b>3$

What if we have some money involved?

What if we have some money involved? $\text{Cost} = \$5$ . That should be fine, right? $\$100$ .

How about standalone ones?

And multi-line?

What if I leave blank lines?

OK, now we’re cooking.

How about a circuit?

Let’s do serious equation things:

We could equivalently write this matrix equation even more compactly as an augmented matrix as described in the Systems of Equations section:

## Inline Math! & 5 < 3 > x

Before $x$ , between $x \rightarrow \infty$ .

In fact, depending on the structure of our equations and for really huge values of $x$ , it might be appropriate (though usually is not!) to take the full limit of $x \rightarrow \infty$ :

…

For “small” $x$ , by which we really mean $|x| \ll 1$ , a new approximation is needed for our function $y(x) = \frac {1} {1 + x}$ .

…

But, for values of $x$ close to 1, we can approximate this fraction with a simpler expression that doesn’t have an $x$ in the denominator. Here’s how we can construct the tangent line around the point $x=1$ :
