A simple approximation of the first derivative is f0(x) ≈ f(x+h)−f(x) h, (5.1) where we assume that h > 0. What do we mean when we say that the expression on the right-hand-side of (5.1) is an approximation of the derivative? For linear functions (5.1) is actually an exact expression for the derivative. For almost all other functions,

The derivative of a function f with respect to the variable x is the function f ' whose value at x is () ()() 0 'lim h f xh fx fx h +-= , provided the limit exists. Anywhere that the derivative exists, we say that the function is differentiable. Thus the derivative is a function that gives the slope of the function at any point.

Then the derivative f′ is a function of x and if f′ is differentiable at x, then the derivative of f′ at x is called second derivative of f at x. It is denoted by f″(x) or f(2)(x).similarly, if f” is differentialble at x , then this derivative is called the 3rd derivative of f and it is denoted by f(3)(x).

prisingly, we call this new function the derivative of f(x). Thus, The derivative of a function y = f(x) is the function defined by f0(x) = lim h→0 f(x+h)−f(x) h. So the derivative f0(x) of a function y = f(x) spews out the slope of the tangent to the graph y = f(x) at each x in the domain of f where there is a tangent line.

De nition: Let f(x) be a function of x, the derivative function of f at xis given by: f0(x) = lim h!0 f(x+ h) f(x) h If the limit exists, f is said to be di erentiable at x, otherwise f is non-di erentiable at x. If y= f(x) is a function of x, then we also use the notation dy dx to represent the derivative of f. The notation is read "D yD x".
