nilai dari :
[tex] \frac{sin \: 45.cos \: 30. \: tg \: 210}{tg \: 30.sin \: 240.cos \: 315} [/tex]


​

Jawaban:

-1

Penjelasan dengan langkah-langkah:

SOAL:

[tex] \frac{ \sin(45) \cos(30) \tan(210) }{ \tan(30) \sin(240) \cos(315) } = [/tex]

JAWAB:

[tex] \frac{ \sin(45) \cos(30) \tan(180 + 30) }{ \tan(30) \sin(180 + 60) \cos(360 – 45) } = [/tex]

[tex] \frac{ \sin(45) \cos(30)\ tan(30) }{ \tan(30) ( – \sin(60)) \cos(45) } = [/tex]

[tex] \frac{ \cos(30) }{ – \sin(60) } = \frac{ \cos(90 – 60) }{ – \sin(60) } = \frac{ \sin(60) }{ – \sin(60) } = – 1[/tex]
