WebSep 13, 2024 · September 13, 2024 Calculus / Mathematics Using the First Principle of Derivatives, we will prove that the derivative of cot ( x) is equal to − 1 / sin 2 ( x). The derivative of cotangent is easier to prove if we take its identity, which is the inverse of the tangent. Proof. Let f ( x) = cot ( x) = 1 tan ( x) = cos ( x) sin ( x). Then WebI have always seen the derivative of tan (x) as sec^2 (x) and the derivative of cot (x) as -csc^2 (x). This seems to be the standard, and I have never seen it otherwise. However, Sal is using 1/cos^2 (x) as the derivative of tan (x) and -1/sin^2 (x) as the derivative of cot (x).
