Concept of derivative...

Move  T to get various position 
of the tangent  .Plz observe the line formed 
by tracing the points (x,m) where m is the 
slope of the tangent -it's the derivative 
of the given function

y =  x - 3
which is nothing but 
f'(x), the derivative of the given curve

f(x) = x^(2) / 2 - (3 * x) + 8
b = 4.2 (slider from -1 to 15, step 1.0E-5)
A: (b, f(b))
c = Tangent(A, f)
m = Slope(c)
B: (b, m)
C: (b, 0)
d = Segment(B, C)
D = Midpoint(C, B)
