Question

Чему равны сos п/6,sin п/6, tg п/6, ctg п/6

Answer 1

Cos π/6=√3/2
sin π/6=1/2
tg π/6=(1/2) / (√3/2)=1/√3=√3/3
ctgπ/6=(√3/2) / (1/2)=√3

Answer 2

cos(π/6) = √3/2 sin(π/6) = 1/2 tg(π/6) = sin(π/6) / cos(π/6) = (1/2) / (√3/2) = 1/√3 = √3/3 ctg(π/6) = cos(π/6) / sin(π/6) = (√3/2) / (1/2) = √3

Таким образом, cos(π/6) = √3/2, sin(π/6) = 1/2, tg(π/6) = √3/3, ctg(π/6) = √3.
