hasil dari fraction numerator tan open parentheses 60 degree close parentheses minus 2 cos open parentheses 60 degree close parentheses over denominator sin squared open parentheses 45 degree close parentheses end fraction equals 2 open parentheses square root of 3 minus 1 close parentheses.

Pembahasan

Ingat bahwa:

  • table attributes columnalign right center left columnspacing 0px end attributes row cell tan open parentheses 60 degree close parentheses end cell equals cell square root of 3 end cell row cell cos open parentheses 60 degree close parentheses end cell equals cell 1 half end cell row cell sin open parentheses 45 degree close parentheses end cell equals cell fraction numerator square root of 2 over denominator 2 end fraction end cell end table 

Sehingga:

fraction numerator tan open parentheses 60 degree close parentheses minus 2 cos open parentheses 60 degree close parentheses over denominator sin squared open parentheses 45 degree close parentheses end fraction equals fraction numerator square root of 3 minus 2 times 1 half over denominator open parentheses fraction numerator square root of 2 over denominator 2 end fraction close parentheses squared end fraction equals fraction numerator square root of 3 minus 2 times 1 half over denominator 1 half end fraction equals fraction numerator square root of 3 minus 1 over denominator 1 half end fraction equals fraction numerator open parentheses square root of 3 minus 1 close parentheses times 2 over denominator 1 end fraction equals 2 open parentheses square root of 3 minus 1 close parentheses 

Jadi, hasil dari fraction numerator tan open parentheses 60 degree close parentheses minus 2 cos open parentheses 60 degree close parentheses over denominator sin squared open parentheses 45 degree close parentheses end fraction equals 2 open parentheses square root of 3 minus 1 close parentheses.
