Computer algebra via the 'SymPy' library (<https://www.sympy.org/>).
This makes it possible to solve equations symbolically,
find symbolic integrals, symbolic sums and other important quantities.

<dl><dt>x</dt>
<dd>A <code>caracas_symbol</code></dd>
<dt>...</dt>
<dd>Pass on to SymPy's expand, e.g. <code>force = TRUE</code>
if (has_sympy()) 
def_sym(x)
y &lt;- log(exp(x))
simplify(y)
expand(simplify(y))
expand(simplify(y), force = TRUE)
expand_log(simplify(y))</dd></dl>
