Figure 2.1: Given a function f (x ), if one can “zoom



in” on f (x ) sufficiently so that f (x ) seems to be a

straight line, then that line is the tangent line to

f (x ) at the point determined by x .

at two points. The slope of any secant line that passes through the points (x, f (x ))

and (x + h, f (x + h )) is given by

∆y

∆x =

f (x + h ) − f (x )

(x + h ) − x =

f (x + h ) − f (x )

h ,

see Figure 2.2. This leads to the limit definition of the derivative :

Definition of the Derivative The derivative of f (x ) is the function

d

dx f (x ) = lim

h →0

f (x + h ) − f (x )

h .

If this limit does not exist for a given value of x , then f (x ) is not diff erentiable

at x .
