Larger slanted arrow?

Question

I'm looking to write something like $\longsearrow quad \nearrow$

how can I achieve this?

p.s. It seems like this \newcommand{\bigarrow}{\mbox{\larger$\searrow$}} doesn't work, or am I doing it wrong?

Thanks in advance!

Answer 1

One possibility is to take an xrightarrow, make it longer with some phantom text, and rotate it. However, this is not a very clean solution, and the rotating clearly shows the segments of the xrightarrow, which does not look good.

An alternative is to use tikz to draw two arrows in a coordinate system.

MWE:

\documentclass{article}
\usepackage{graphicx} % for \rotatebox
\usepackage{amsmath} % for \xrightarrow
\usepackage{tikz}

\def\arrowrotate{\rotatebox[x=0mm,y=20mm]{-35}{$\xrightarrow{\phantom{xxxx}}$} \nearrow}
\def\arrowtikz{\ \tikz{\draw[->] (0.2,0.25) -- (0.5,0); \draw[->] (0.6,0) -- (0.8,0.15);}\ }

\begin{document}
We define some things.

We define $A \arrowrotate B$.

We define $C \arrowtikz D$.
\end{document}

Result:

The xrightarrow approach can be customized by adjusting the number of x characters (for the length of the arrow), the rotate angle (here -35), and the vertical position of the first arrow (here 20mm).

The tikz approach can be customized by changing the coordinates, changing the amount of space (here the control space \ left and right, see What commands are there for horizontal spacing?) and possibly the size and shape of the arrow tip (see https://tex.stackexchange.com/a/161238/).
