Bantu dong buat dikumpulkan besok [tex] (cos \frac{11}{6} \pi + sin \frac{\pi}{3} ) \div (tan \frac{\pi}{6} + cot \frac{4}{3} \pi)[/tex]

11/6 π = 11/6 × 180° = 330°
cos 330° = cos 30° = 1/2 √3

sin (π/3) = sin (180°/3) = 1/2 √3

tan (π/6) = tan (180°/6) = 1/√3

cot (4/3 π) = cot 240° = 1/√3

soal
= (1/2 √3 + 1/2 √3) : (1/√3 + 1/√3)
= √3 × √3/2
= 3/2
