WebSep 7, 2024 · Find the derivative of h(x) = sec(4x5 + 2x). Solution Apply the chain rule to h(x) = sec (g(x)) to obtain h ′ (x) = sec(g(x))tan (g(x)) ⋅ g ′ (x). In this problem, g(x) = 4x5 + 2x, so we have g ′ (x) = 20x4 + 2. Therefore, we obtain h ′ (x) = sec(4x5 + 2x)tan(4x5 + 2x)(20x4 + 2) = (20x4 + 2)sec(4x5 + 2x)tan(4x5 + 2x). Exercise 3.6.3
