Derivative of Sec X is equal to sec x. tan x. To find the derivative of sec x we use the first principle method of derivative calculus.In this video lesson of derivative calculus we prove the derivative of sec X and also watch the graph of sec which makes us easy to understand the real meaning of Derivative of sec X.
I hope after learning this video lesson of derivative of sec x you understand how to prove the derivative of sec x = sec x . tan x
