sin(a)^2 + cos(a)^2 = 1 => 1/36 + cos(a)^2 = 36/36 => cos(a)^2 = 35/36 => cos(a) = Корен(35) / 6
tg(а) = sin(a) / cos(a) => tg(a) = 1 / Корен(35)
sin(a)^2 + cos(a)^2 = 1 => 1/36 + cos(a)^2 = 36/36 => cos(a)^2 = 35/36 => cos(a) = Корен(35) / 6
tg(а) = sin(a) / cos(a) => tg(a) = 1 / Корен(35)
Tg a=sin a/cos a
Tg a=1/sqrt(35)=sqrt35/35
