Question

Значення синуса,косинуса і кутів 30,45,60.

Answer 1

tg (30°) = tg (π/6) = (√3)/3 = 1/√3 tg (45°) = tg (π/4) = 1 tg (60°) = tg (π/3) = √3 сos (30°) = cos (π/6) = (√3)/2 сos (45°) = cos (π/4) = (√2)/2 = 1/√2 сos (60°) = cos (π/3) = 1/2 sin (30°) = sin (π/6) = 1/2 sin (45°) = sin (π/4) = (√2)/2 = 1/√2 sin (60°) = sin (π/3) = (√3)/2
