Parametric Equations (CAS)

[skorm123]

Can anybody tell me how I can draw parametric equations on my CAS. Any help is much appreciated, thanks.

which one do you have?

For the Nspire:
Graphmenu 3 2
Make sure you know the domain of t - for safety, type in a domain much bigger than you need.

If its the Ti-nspire there is a link to a guide in my sig below (includes pics).

But anyway, when you are on the graph page with the vetical line in the entry bar, click [Ctrl] + [Menu] whihc will bring up a dialog box, then select [2] graph type and [2] for parametric equations. Then the x or the i component goes in the x1(t) (in terms of t) and the y or the j component goes in the y1(t).

EDIT: beaten

eqns:
x= (2e^0.3t)cos(2t)
y=(2e^0.3t)sin(2t)
0<=t<=2pi
Thanks so much, I was doing kilbaha and got stuck on this one equation where I couldn't seem to rearrange it. Btw its a pretty cool graph looks like a rose.

Lol, they are the same as the example in my guide (the spesh one).

xD I was doing kilbaha and this question came up, completely stumped me. Thanks for the help I will remember to look into your guide some more for future reference. Now that I think about it I might just stick a lot of those shortcuts on my bound reference.

wait you can graph y= shit on your calcs
shoulda bought a new one, dayum

edit: x=* oops

Can't all CAS calculators graph parametric equations?

1. idk what cas is, but i use this massive black calc, it is called Darius
2. idk what parametric is
3. i press the green button then f1 and then i type in whatever y is, it dun got no x column brooooooooo

you have a ti-89. Press mode -> graph type -> parametric

Can you do this on the casio class pad?

I think paulsterio's the guy to talk to for the classpad!

For the classpad, go to the basic graph menu. In the second row of tabs (just below edit and type), it says "y=." Click on the arrow to the right of that button and there will be a drop down list. Then click on xt (top right) and then enter your parametric equations.
