1. The problem statement, all variables and given/known data
use the definition of derivative to find the derivative of tan(x)


2. Relevant equations

Tan(x)= sinx/cosx

3. The attempt at a solution

i used sinx/cosx, and then use quotient rule, not sure if it is call "definition of derivative"so, is there anyway i can use f(x+h)-f(x)/h to find the derivative of tan (x)?
