Find the Derivative d/dx y=2sec(x)tan(x) Since is constant with respect to , the derivative of with respect to is Differentiate using the Product Rule which states that is where and The derivative of with respect to is Multiply by by adding the exponents From above, we found that the first derivative of sec^2x = 2sec 2 (x)tan(x) So to find the second derivative of sec^2x, we need to differentiate 2sec 2 (x)tan(x) We can use the product and chain rules, and then simplify to find the derivative of 2sec 2 (x)tan(x) is 4sec 2 (x)tan 2 (x) 2sec 4 (x)This proves from first principles that the derivative of tan x is sec^2x Approved by eNotes Editorial Team We'll help your grades soar Start your 48hour free trial and unlock all the
Integration goes the other way the integral (or antiderivative) of 1 / x should be a function whose derivative is 1 / x\( \frac{d}{dx} {tanx} = \frac{d}{dx} \frac{sinx}{cosx}\) we know that \( tanx =\frac{sinx}{cosx If we zone in on − π 2 ≤ x ≤ π 2, then we see that the value of sec 2 ( x) is greater as we approach x = − π 2 or x = π 2 This is because we can think of the derivative as slope and previously saw that the slope was greatest near the asymptotes Therefore, it is natural for sec 2
Just for practice, I tried to derive d/dx (tanx) using the product rule It took me a while, because I kept getting to (1sin^2 (x))/cos^2 (x), which evaluates to sec^2 (x) tan^2 (x) Almost there, but not quite After a lot of fiddling, I got the correct result by adding cos^2 (x) toThe derivative of tan x, sec x & tan x – The derivative of a function of a real variable measures the sensitivity to change of the function value (output value) with respect to a change in its argument (input value) Derivatives are a fundamental tool of calculus For example, the derivative of the position of a moving object with respect to time is the object's velocity this measures howI prefer to write sin x tan x as (sin x)^2 / cos x = 1/cos x (cos x)^2 / cos x = sec x cos x simply differentiate to get y' = sec x tan x sin x = (sin x) ( (sec x)^2 1) = sin x ((tan x)^2 2) in terms of our original variables Extra c

Dy/dx is nothing but the rate of change of y with respect to the change in the value of x ie if ∆x is a very small change in the value of x ,the corresponding change in the value of y is ∆y, then dy/dx = limit ∆x tends to 0 ∆y/∆x iedy/dx = limitIf the derivative of a is b, then the integral of b is a C, where C is a constant This tells us that to check our work, we can take the integral of 2sec 2 x tan x, and we should get sec 2 x Transcribed image text Question 8 Find the derivative of f(x) =e4x sec2x Oa f'(x) =4 e4x sec 2x 2 e4x sec 2x tan 2x Obf'(x) = e46 sec 2X – 24x sec 2x tan 2x Ocf'(x)=4 e 4x sec 2x e4x sec 2x tan 2x Odf'(x) =4 e 4x sec 2x – 2 e4x sec 2x tan

The Derivative of h (x) = 2*sec^2 (x)*tan (x) Product Rule Example Watch later The derivative of the function secant squared of x is d/dx(sec^2(x)) = 2sec^2(x)tan(x) This derivative is obtained by applying the chain rule of differentiation and simplifying the result Sec^2(x) is a composite function that can be rewritten as (sec(x))^2In a previous video we use the quotient rule in order to find the derivatives of tangent of X and cotangent of X and what I want to do in this video is to keep going and find the derivatives of secant of X and cosecant of X so let's start with secant of X the derivative with respect to X of secant of X well secant of X is the same thing as so we're going to find the derivative with
