(*http://www.physicsforums.com/showthread.php?t=441123*)

Use the definition of derivative to find the derivative of tan(x)1. The problem statement, all variables and given/known datause the definition of derivative to find the derivative of tan(x) 2. Relevant equationsTan(x)= sinx/cosx 3. The attempt at a solutioni 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)? |

Re: Use the definition of derivative to find the derivative of tan(x)The question does want you to use (f(x+h)-f(x))/h, which is the definition of the derivative. That's the relevant equation. It might also be handy to have an equation for tan(a+b).
