Talvez deva tentar algumas variações de ortografia:
extraction method » extraction methods (Expandir a busca)
taper functions » transfer functions (Expandir a busca), linear functions (Expandir a busca)
case extraction » cane extraction (Expandir a busca), phase extraction (Expandir a busca), based extraction (Expandir a busca)
functions case » functions are (Expandir a busca), functions and (Expandir a busca), functions at (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
using codigo » using indigo (Expandir a busca), using coding (Expandir a busca), using codium (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( taper functions case extraction method ) OR ( using codigo python python programming ))~.
