WebSal wants to show why the derivative of arctan(x) is 1/(1+x^2), and this method is the easiest way of doing so. Although there probably is a way to simplify cos^2(arctan(x)) to 1/(1+x^2) , I think Sal's way was simplest. WebOct 29, 2024 · Derivative of tan x Proof by First Principle Rule. According to the first principle rule, the derivative limit of a function can be determined by computing the formula: For a differentiable function y = f (x) We define its derivative w.r.t x as : dy/dx = f ' (x) = limₕ→₀ [f (x+h) - f (x)]/h.

Using this information, we can use the chain rule to calculate the derivative of tan x. Let, z = cot x. So, d z d x = – csc 2 x. d d x ( tan x) = d d x ( 1 cot x) = d d x ( 1 z) ⇒ d d x ( tan x) = d d x ( 1 z) Apply the chain rule the we get. = d d z ( 1 z). d z d x. orc 2907.02
