Talvez deva tentar algumas variações de ortografia:
protection method » protection methods (Expandir a busca), projection method (Expandir a busca), projection methods (Expandir a busca)
used protection » user protection (Expandir a busca), uses protection (Expandir a busca), based protection (Expandir a busca)
four functions » floor functions (Expandir a busca), fourier functions (Expandir a busca), flour functional (Expandir a busca)
functions used » functions based (Expandir a busca), functions using (Expandir a busca), functions under (Expandir a busca)
coding python » codigo python (Expandir a busca), codigos python (Expandir a busca), using python (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
using coding » using holding (Expandir a busca), using coupling (Expandir a busca), missing coding (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( four functions used protection method ) OR ( using coding python python programming ))~.
