31 lip 2015 · Use the fact that arctan (1/x) = arc cot (x) and d/dx arc cot (x) = -1/ (1+x^2) to go straight to the answer.
To differentiate it quickly, we have two options: Use the simple derivative rule. Derive the derivative rule, and then apply the rule. In this lesson, we show the derivative rule for tan -1 (u) and tan -1 (x). Additionally, we cover how the derivative rule is derived.
25 mar 2019 · The derivative of the inverse tangent function ($f(x)=\tan^{-1}{x}$), also commonly known as the arctangent function ($f(x)=\arctan{x}$), is: $$\frac{1}{1+x^2}.$$ Period. It's definitely not $\sec^{-2}{x}$ .
