WebJul 11, 2024 · f' (x) = sec x · tan x Thus, we proved the derivative of sec x will be equal to sec x · tan x using the first principle rule method. Derivative of sec x Proof by Chain Rule Let us, y = sec x As we know, sec x = 1/cos x So, y = 1 / (cos x) = (cos x)⁻¹ By using the chain rule, The formula of chain rule is, dy/dx = (dy/du) × (du/dx) Where, WebApr 4, 2024 · 5.

WebDefinition: The derivative of the function f: R → R at a value x = a, if it exists, is lim h → 0 = f ( a + h) − f ( a) h So, you have f ( x) = tan ( x) sec ( x) Let u ( x) = tan ( x) and v ( x) = s e c ( x)? Using first principles, you can derive the equation f ′ ( x) for f ( x) = u ( x) v ( x), because we have: WebDec 23, 2024 · Therefore, to find the derivative of sec 2 x, we take the following steps: Find the derivative of f ( x) = x 2, which is f' ( x) = 2 x. Plug g ( x) = sec x into f' ( x)... fix my teeth
