tan² 30 + tan² 45 + tan² 60 = sin² 30 / cos² 30 + sin² 45 / cos² 45 + sin² 60 / cos² 60
sin 30 = 1/2 = cos 60
sin 60 = √3/2 = cos 30
sin 45 = cos 45 = 1/√2
L H S = (1/√3 )² + 1² + (√3)² = 4 + 1/3 = 13/3
sin 30 = 1/2 = cos 60
sin 60 = √3/2 = cos 30
sin 45 = cos 45 = 1/√2
L H S = (1/√3 )² + 1² + (√3)² = 4 + 1/3 = 13/3
