Pembahasan

Ingat kembali:

2 space cos space straight alpha space cos space straight beta equals 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 cos space 4 straight alpha times cos space 2 straight alpha end cell equals cell 1 half times 2 times cos space 4 straight alpha times cos space 2 straight alpha end cell row blank equals cell 1 half times open parentheses 2 times cos space 4 straight alpha times cos space 2 straight alpha close parentheses end cell row blank equals cell 1 half open parentheses cos space open parentheses 4 straight alpha plus 2 straight alpha close parentheses plus cos space open parentheses 4 straight alpha minus 2 straight alpha close parentheses close parentheses end cell row blank equals cell 1 half open parentheses cos space 6 straight alpha plus cos space 2 straight alpha close parentheses end cell row blank equals cell 1 half space cos space 6 straight alpha plus 1 half space cos space 2 straight alpha end cell end table 

Jadi, nilai table attributes columnalign right center left columnspacing 0px end attributes row blank blank cos end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank space end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank 4 end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank straight alpha end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank times end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank cos end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank space end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank 2 end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank straight alpha end table table attributes columnalign right center left columnspacing 0px end attributes row blank equals blank end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell 1 half end cell end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank space end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank cos end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank space end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank 6 end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank straight alpha end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank plus end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell 1 half end cell end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank space end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank cos end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank space end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank 2 end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank straight alpha end table.
