Here are the given functions:

$ e^x $ $\rm ln $ $ x^2 $ $ \surd$ $\rm sin$ $\rm asin$ $\rm cos$ $\rm acos$ $\rm tan$ $\rm atan$

These functions can be contructed from those:

$ |x| $ $ \, : ~~~ x $ $ x^2 $ $x^2$ $ \surd$ $|x|$ $\raise-1ex\strut$

$ 1{+}x $ $ : ~~~ x $ $ \surd$ $\surd x$ $\rm atan$ $ \theta $ ($\tan \theta = \surd x$) $\rm cos$ $ \frac1{\sqrt{1+x}} $ $\rm ln $ $ -\ln \sqrt{1+x} $
      $ |x| $ (as constructed) $ \ln \sqrt{1+x} $ $ e^x $ $ \sqrt{1+x} $ $ x^2 $ $1+x$

This gets to 3:

0 $ 1{+}x $ 1 $ 1{+}x $ 2 $ 1{+}x $ 3
