Soal MTK ttg trigonometri

2(cos60)²+4(sec30)²-(tan45)²/(sin30)²+(cos30)²
=2(½)²+4(2/√3)²-(1)²/(½)²+(½√3)²
=2(¼)+4(4/3)-1/¼+¾
=½+16/3-1/1
=3+32-6/6
=29/6

maaf kalau salah

2(cos 60°)² + 4(sec 30°)² - (tan 45)² / (sin 30°)² + (cos ⁡30°)²

= 2(1/2 √3)² + 4(2/3 √3)² - (1/2 √2)² / 1

= 2(3/4) + 4(4/3)- (1/2)

= 3/2 + 16/3 -1/2 = (9+32-3)/6 = 38/6= 6 2/6 = 6 1/3
