Sage Tool 1

This Sage file is configured for use as a simple graphing tool.

Define the function $f$ to be graphed, the center point $c$ of the domain, and the width $w$ of the interval.  You can zoom in or out by changing the value of $w$.

var('t')
@interact
def _(f=4.90*t^2,c=2,w=10):
    g=str(f).strip('*')
    html('f(t) is $%s$'%g)
    html('c is %s'%c)
    html('w is %s'%w)
    show(plot(f,c-w/2,c+w/2))
