On-line help: Al Lehnen
has prepared a detailed guide
to Winplot

Initial examples:
-
Equa
Menu
-
Plot a function :explicit... y
= f (x)...
-
f(x) = x sin(x)
-
f(x) = 2x-4
-
f(x) = x^2 - 4
-
f(x) = x^3 - 2
-
Plot a point : Point...
-
(1,3)
-
(a,b), (a, a^2), (a, f(a))
-

Compare:
-
graph of x3 with graph of 2x3
-
graph of x2 with graph of 3x2
-
graph of x2 with graph of (x+1)2
-
graph of x3 with graph of (x+1)3
-
Graphs of x2
Discuss how each constant A, B, and C effects the graph.[>1, >0,
<0.]
-
f(x)= Ax2
