multiple parametric equations
Can anyone explain how it works when you graph multiple equationsin parametric mode?
Example:
3.3 #99
Example:
3.3 #99

this took me a long time to figure out.
so this is what you do:
3.3.99
x=(t^2-1)(t^2-4)(t+5)+t+3
y=(t^2-1)(t^2-4)(t^3+4)+t-1
ofcourse you know to get into parametric mode you go to the y= screen hit the "mode" key and change function to parametric where it says "graph" and hit enter.
now type in:
1) for x=(t^2-1)(t^2-4)(t+5)+t+3
xt1=(t^2-1)(t^2-4)(t+5)+t+3
yt1=t
2) for y=(t^2-1)(t^2-4)(t^3+4)+t-1
xt2=t
yt2=(t^2-1)(t^2-4)(t^3+4)+t-1
if step 2 doesn't read, then try typing in
xt2=t
yt2=f(x)=(t^2-1)(t^2-4)(t^3+4)+t-1
the calculator might ask you to "define" it so just delete the f(x) and graph.
dont forget to put in the constraints for t in the "window" screen
hope thats helpful!
