I'm trying to "hide" and answer by rotating it 180 degrees.

Using `\rotatebox`

works fine if I have a short answer:

```
\rotatebox{180}{The answer is $\pi$}
```

However, if I want to put a `\begin{equation}...\end{equation}`

or maybe rotate a whole paragraph I get errors:

```
\rotatebox{180}{
\begin{equation}
\sin^2+\cos^2 = 1
\end{equation}
```

}

gives: `ERROR: Missing $ inserted.`

while

```
\rotatebox{180}{a
b
c
}
```

gives: `ERROR: Paragraph ended before \Grot@box@std was complete.`

Is there a better command to be using? or a way to make `\rotatebox`

work for these cases?

PS. I tried using the `turn`

environment of `rotating`

, but while it compiled, it didn't give the desired outcome.

PPS. I tried using the packages listed in this question….to no avail.

You could use a

`\vbox`

(or a`\parbox`

or a`minipage`

) to box the equation:
