Производная.. надо.. на оценку..если не можете все то хотя бы часть 1) f(x) = 4 x - sin x 2) f(x) = tg x - 4 ctg x 3) f(x) = 6 cos x - 1.2x 4) f(x) = cos (x - π\6) 5) f(x) = ctg (π\6 + x) 6) f(x) = sin (π\4 - x) 7) f(x) = tg (x + π\3) 8) f(x) = -sin 2x - cos 2x 9) f(x) = x^2 + 2 cos x 10) f(x) = x^3 - tg 4 x 11) f(x) =2 ctg 3 x + 0.5x^4 12) f(x) = x\ sin x 13) f(x) = cos x \ x 14) f(x) = xtg x 15) f(x) = xctg x
