Mastering The Chain Rule Of Differentiation For Sec X: Derivative Simplified

d/dx (secx)=

secx×tanx

Using the chain rule of differentiation, we can find the derivative of sec x with respect to x as follows:

Let y = sec x

Then, we can rewrite y as y = 1/cos x

Now, we can use the quotient rule to differentiate y with respect to x as follows:

d/dx (1/cos x) = (-1/cos^2 x) * (-sin x)

= sin x/cos^2 x

= sin x * sec^2 x

Therefore, d/dx (sec x) = sin x * sec^2 x
