Hi,
Try the following : Clear[Evaluate[ToString[$Context]<>"*"]]
Example
In[1]:=
f[x_]:=Sin[x]
f[2.]
Clear[Evaluate[ToString[$Context]<>"*"]]
f[2]
Out[2]= 0.909297
Out[4]= f[2]
Definition of f, is cleared; this will clear all symbols from the current
context (the one you are working). Mathematica provides the syntax
Clear["context`*"] to clear all symbols in
a particular context.
