As the function atan2 is a function of two variables, it has two partial derivatives.At points where these derivatives exist, atan2 is, except for a constant, equal to arctan(y/x).Hence for x > 0 or y ≠ 0, ∂ ∂ ⁡ (,) = ∂ ∂ ⁡ = − +, ∂ ∂ ⁡ (,) = ∂ ∂ ⁡ = +. Consider the function y = arctan 1 − x 1 + x. Differentiate both sides with respect to x, d d x (y) = d d x (arctan 1 − x 1 + x) d d x (y) = d d x (tan − 1 1 − x 1 + x) Recall that differentiation rule for inverse trigonometric functions is d d x (tan − 1 x) = 1 1 + x 2. The derivative of arctan(x) = 1/(x^2 + 1), so we're going to use this general formula. The second derivative for arctan is \\frac{-2x}{(1+x^2)^2} No problem. Let y = arctan(y) Then x = tan(y) Using implicit differentiation: 1 = dy/dx * (sec^2(x)) Since sec^2(z) = 1 + tan^2(z).....(see below end of proof) Replace all occurrences of with . Differentiate functions that contain the inverse trigonometric functions arcsin(x), arccos(x), and arctan(x). 1 Answer Jim G.
