1.2.3.4.5.6.7.8.Part A
(D) as x → 2.(A) Divide both numerator and denominator by .(D) Since eln u = u, y = 1.(D) f(0) = 3, and f ′(x) = (9 + sin 2x)−1/2 · (2 cos 2x), so f ′(0) = ; y
x + 3.(A) arctan arctan .(D) Here y′ = 3 sin^2 (1 − 2x) cos (1 − 2x) · (−2).(B).(B) Let s be the distance from the origin: then
