# Line Space

#### zylo

How do you add a line space? Thanks

Code:
$$\displaystyle P=\begin{bmatrix} 1 &1 \\ \sqrt{5}& -\sqrt{5} \end{bmatrix}, \quad P^{-1} = \frac{1}{2\sqrt{5}} \begin{bmatrix} \sqrt{5}& 1\\ \sqrt{5} & -1 \end{bmatrix}, \quad T= \begin{bmatrix} 1 & 1\\ 5 & 1 \end{bmatrix}\\ P^{-1}TP=\begin{bmatrix} 1+\sqrt{5} & 0\\ 0 & 1+3\sqrt{5} \end{bmatrix}$$

Try using "\\[6ex]" instead of "\\".

$$\displaystyle P=\begin{bmatrix} 1 &1 \\ \sqrt{5}& -\sqrt{5} \end{bmatrix}, \quad P^{-1} = \frac{1}{2\sqrt{5}} \begin{bmatrix} \sqrt{5}& 1\\ \sqrt{5} & -1 \end{bmatrix}, \quad T= \begin{bmatrix} 1 & 1\\ 5 & 1 \end{bmatrix}\\ \\ [6ex] P^{-1}TP=\begin{bmatrix} 1+\sqrt{5} & 0\\ 0 & 1+3\sqrt{5}$$

\end{bmatrix}

\\[6ex] works
\\[12ex] (shown) works more.

Many Thanks!

Well anyhow, worked in first preview, then I lost it. Probably something I missed.
