Derivative of secx 10 Derivatives of tan(x), cot(x), sec(x), and csc(x) Next Lesson. Find the formula, proof and examples of derivative of sec x and related topics. 5. See the formula, the proof, and the derivative rules of other trig functions. Let’s begin – Differentiation of secx. We know that sec x is the reciprocal identity of cos x, that is, secx = 1/cosx. When both u and v are the functions of x, formula to find the derivative of u with respect to v : Substitute u = t anx, v = secx, ᵈᵘ⁄ d ₓ = sec 2 x and ᵈⱽ⁄ d ₓ = secxtanx. The Derivative tells us the slope of a function at any point.
