Master The Quotient Rule: Derivative Of Tan X | Seo-Optimized Math Tutorial.

Derivative of tan x

sec^2 x

The derivative of tan x can be found using the quotient rule. Let y = tan x.

y’ = d/dx(tan x)

Using the quotient rule:

y’ = [(sec x)^2 * d/dx(x) – (tan x)(d/dx(sec x)^2)] / (sec x)^4

Simplifying:

y’ = [(sec x)^2 – (tan x)(2 sec x tan x)] / (sec x)^4

y’ = sec x / (cos x)^2

Therefore, the derivative of tan x is sec x / (cos x)^2.
