Basic Function Graphing I
The example in this section demonstrates some of the graphing
capabilities of the TI-89 Titanium keystrokes. It illustrates how to graph a
function using the
Y= Editor. You will learn how to enter a function,
produce a graph of the function, trace a curve, find a minimum point,
and transfer the minimum coordinates to the Home screen.
Explore the graphing capabilities of the TI-89 Titanium by graphing the
function y=(|x
2
N3|N10)/2.
4. Using the same m, calculate the force for an
acceleration due to gravity (the constant
_g).
For _g, you can use the pre-defined
constant available from the
UNITS dialog
box or you can type _g.
