Asked by K
I know the derivative of x is 1, but I'm having a hard time proving it with the limit definition of the derivative.
I have...
Lim delta x ->0 (x+ delta x)-(x)/delta x
= 0
But I know the answer is 1. I don't understand what I am doing wrong

(f(x+h) - f(x))/h
= ((x+h)-x)/h
= h/h
= 1
no need even to take the limit, since 1 is constant.
