Perhaps you should try some spelling variations:
funcoes matematica » functions mathematics
matematica della » matematici della, matematica nella, matematiche dalla
una matematica » la matematica, a matematica, munari matematica
tra matematica » la matematica, a mathematica, e matematica

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: "((((\"lecture notes of the funcoes matematica della\") or (\"lecture notes of the ((functions mathematical) OR (equations mathematical)) della\"))) or (\"lecture notes of the ((una matematica) OR (tra matematica)) della\"))".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((((\\"lecture notes of the funcoes matematica della\\") or (\\"lecture notes of the ((functions mathematical) or (equations mathematical)) della\\"))) or (\\"lecture notes of the ((una matematica) OR (tra matematica)) della\\"))\"".
• Removing quotes may allow a broader search: (((( lecture notes of the funcoes matematica della ) or ( lecture notes of the ((functions mathematical) or (equations mathematical)) della ))) or ( lecture notes of the ((una matematica) OR (tra matematica)) della )).
