Few examples

Trigonometric functions

Turn this :

#import "@preview/vartable:0.2.4": tabvar

#tabvar(

  variable: $x$,
  label: (
    ([sign of cos’], "s"),
    ([variation of cos], "v"),
    ([sign of sin’], "s"),
    ([variation of sin], "v"),
  ),

  domain: ($0$, $ pi / 2 $, $ pi $, $ (2pi) / 3 $, $ 2 pi $),
  contents: (
    ($-$, (), ("0",$+$), ()),
    (
      (top, $1$),
      (),
      (bottom, $-1$),
      (),
      (top, $1$),
    ),
    ($+$, $-$, (), $+$),
    (
      (center, $0$),
      (top, $1$),
      (),
      (bottom, $-1$),
      (center, $0$),
    ),
  ),
  values: (
    ("arrow10.50%", $  $, $ 0 $, "f"),
    ("arrow12.49%", $  $, $ 0 $, "f"),
  )
)

Into this

hyperbolic function $f(x) = 1/x $

#import "@preview/vartable:0.2.4": tabvar

#tabvar(
  arrow-mark: (end: ">", start: "|"),
  variable: $x$,
  label: (
    ([sign of $f’$], "s"),
    ([variation of $f$], "v"),
  ),
  domain: ($ -oo $, $ 0 $, $ +oo $),
  contents: (
    ($+$, ("||", $+$)),
    (
      (center, $0$),
      (bottom, top, "||", $ -oo $, $ +oo $),
      (center, $ 0 $),
    ),
  ),
)

A random function : $f(x) = \sqrt{x²-4}$ & $f'(x) = \frac {x} {\sqrt{x² - 4}}$

#import "@preview/vartable:0.2.4": tabvar, hatch

#tabvar(
  variable: $t$,
  label: (
    ([Sign of $f’$], 1cm,"s"),
    ([Variation of $f$], "v"),
  ),
  hatching-style: hatch,
  domain: ($ -oo $,($ -2 $, 1cm),$ 2 $, $ +oo $),
  contents: (
    ( $ - $, "|h|", $ + $), 
    (
      (top, $ +oo $),
      (bottom,"|h", $ 0 $), 
      (bottom, "H|", $ 0 $),
      (top, $ +oo $)
    )
  )
)
