f(x)=lim_(h rarr0)(f(n+h)-f(n))/(h)

lim_(h rarr0)(sin h)/(h)

If f(x)=(1)/(x), evaluate lim_(h rarr0)(f(x+h)-f(x))/(h)

Let f be differentiable at x=0 and f'(0)=1 Then lim_(h rarr0)(f(h)-f(-2h))/(h)=

If f(x) is a differentiable function of x then lim_(h rarr0)(f(x+3h)-f(x-2h))/(h)=

If is an even function such that lim_(h rarr 0) (f(h)-f(0))/(h) has some fininte non-zero value, then

If f is an even function such that lim_(h rarr0)(f(h)-f(0))/(h) has some finite non-zero value,then prove that f(x) is not differentiable at x=0.

lim_(h rarr0)(sin(x+h)-sinx)/(h)

D*f(x)=lim_(h rarr0)(f^(2)(x+h)-f^(2)(x))/(h) If f(x)=x ln x then D*f(x) at x=e equals
