Ingat kembali: Maka: Jadi, nilai .

Ingat kembali:

2 space sin space straight alpha space sin space straight beta equals negative cos space open parentheses straight alpha plus straight beta close parentheses plus cos space open parentheses straight alpha minus straight beta close parentheses 

Maka:

table attributes columnalign right center left columnspacing 0px end attributes row cell sin space 3 over 2 straight alpha times sin space 1 half straight alpha end cell equals cell 1 half times 2 times space sin space 3 over 2 straight alpha times sin space 1 half straight alpha end cell row blank equals cell 1 half times open parentheses 2 times space sin space 3 over 2 straight alpha times sin space 1 half straight alpha close parentheses end cell row blank equals cell 1 half open parentheses negative cos space open parentheses 3 over 2 straight alpha plus 1 half straight alpha close parentheses plus cos space open parentheses 3 over 2 straight alpha minus 1 half straight alpha close parentheses close parentheses end cell row blank equals cell 1 half open parentheses negative cos space 4 over 2 straight alpha plus cos space 2 over 2 straight alpha close parentheses end cell row blank equals cell 1 half open parentheses negative cos space 2 straight alpha plus cos space straight alpha close parentheses end cell row blank equals cell negative 1 half space cos space 2 straight alpha plus 1 half space cos space straight alpha end cell end table
