is a derivative is defined by taking limits
Hello student ,
a derivative is Defined by just taking limit. It is the formal definition of derivative. The derivative of f(x) with respect to x is the function f'( x )it is defined as
f'(x) =lim(h-->0) [{f(x+h) -f(x) }/h]
In this way we can define the derivative. we often read "f'(x) as " f prime of x"
hope this will help you
