Find the corners of a curve

Contributed by: Wolfram|Alpha Math Team

ResourceFunction["FunctionCorners"][c,x]

returns the corners of the curve c viewed as a function of x.

Details and Options

A corner is a point where two branchs of a curve meet and the tangents of each branch are not necessarily equal.

Examples

Basic Examples (1) 

Compute the corners of a curve:

In[1]:=
ResourceFunction["FunctionCorners"][ArcTan[Log[Abs[x]]], x]
Out[1]=

Possible Issues (1) 

Note that corners are more general than cusps:

In[2]:=
ResourceFunction["FunctionCorners"][Abs[x], x]
Out[2]=
In[3]:=
ResourceFunction["FunctionCusps"][Abs[x], x]
Out[3]=
