WebThere is a nice method to get the derivatives of all orders of arctan: write 1 1 + x 2 = 1 2 i ( 1 x − i − 1 x + i) and blindly differentiate as if i ∈ R. Of course this can be made rigorous. ADD A slick solution is the following: 1 1 + x 2 = ∑ k = 0 ∞ ( − 1) k x 2 k It follows (by uniqueness of representation) that if f ( x) = 1 1 + x 2, WebAug 10, 2015 · Explanation: Recap that d dx arctan(x) = 1 1 + x2. By the chain rule, if y is a function of u and u is a function of x, then dy dx = dy du ⋅ du dx. Let u = 6x ⇒ du dx = 6. y = arctan(6x) = arctan(u) ⇒ dy du = 1 1 + u2. Therefore by the chain rule, dy dx = dy du ⋅ du dx. d dx (y) = 1 1 +u2 ⋅ 6. Re-substituting u = 6x and y = arctan(u ...

WebJun 14, 2024 · Use the inverse function theorem to find the derivative of g(x) = x + 2 x. Compare the resulting derivative to that obtained by differentiating the function directly. Solution The inverse of g(x) = x + 2 x is f(x) = 2 x − 1. We will use Equation 3.8.2 and begin by finding f′ (x). Thus, f′ (x) = − 2 (x − 1)2 and phillip and derek houston
