TI-89 and Ap Calculus?

Test Preparation
1

<p>How do I graph X= 1-t, y= 1+t on a TI-89 Graphing Calculator?(Parametric Equations) </p>

<p>Thanks.</p>

2

<p>x = 1- t --> t = 1-x
y = 1+t --> y = 1 + (1-x) --> y= 2-x</p>

<p>But I'm sure there's a way to graph it parametrically.</p>

<p>Yes, there is. Go to MODE then select PARAMETRIC under the first drop-down menu (I think it's the first). Then go to the "y=" editor and you can enter your parametric equations.</p>

<p>By the way, does anyone know if implicit functions can be graphed on an 89?</p>

4

<p>Implicit functions can be graphed on an TI-89, but you would not want to do that - too slooooow.</p>

5

<p>how do you graph implicit?
Do you simply solve for y and copy-paste all the functions?</p>

<p>some equations you just can't solve for y</p>
