Question

Help with Parametric Equation

Answer 1

I need help with example #11

Answer 2

I don't understand what the book is saying

Answer 3

whoops I need help with example #12

Answer 4

oh that is because this is the easiest one. the others are harder. you already have y in terms of x, i.e. y is a function of x. so if you replace x by t you get
\[x=t\]
\[y=t^3-t\] you really don't even need the t, but you are making a "parametric equation"

Answer 5

but what is it saying abt going from righ tto left and left to right I am confused

Answer 6

for example if i want a parametric equation for
\[y=2x+1\] i say
\[x=t, y = 2t+1\]and i am done

Answer 7

but what abt the direction of the curve

Answer 8

in this case we get a direction because we are thinking of t as "time" apparently and time gets larger.

Answer 9

so since x = t as t gets bigger so does x.

Answer 10

that is the "left to right" business x is going from left to right

Answer 11

oh thanks this book is so annoying

Answer 12

yes i think that you might have gotten confused because this example was too easy. other were harder

Answer 29

But I can't understand why you would try such a thing. All I've ever tried to do is help you

Answer 30

oh man i was joking. If a/t wld become serious i wld have said the truth

Answer 31

But then he would have banned you. Then we both would be banned. You can't joke around like that. Owlfred will really ban you

Answer 32

He's one of the owners of this site

Answer 33

ya i know i doubt he wld have banned

Answer 34

You apparently don't know....

He's banned everyone who is already banned.

You don't hear anything about it because those who are banned are banned forever. Plus they don't who exactly banned them. The person that banned them don't come out and say, "yeah, I banned you". And those who are banned are i.p. banned so it's not like they say "Oh I got banned yesterday". Once they're gone, that's it. You don't hear anything about it. Just because he acts nice, doesn't mean he won't ban anybody.

Answer 35

Most of the time when he comes on here, he does a greeting and everyone is like "Yay, Owlfred is here". But his real motive is to come on here and see how everyone is doing, and see if everything is going okay. If not, then, he'll be looking for who is causing trouble, and ban them if necessary

Answer 36

Well then I wld stick up for u. And if i get banned then I don't know i wld email theknow

Answer 37

Well, I'm just warning you just in case you decide to tell another joke about someone while owlfred is here.

Answer 38

This site is terrible today

Answer 39

alrighty i won't do it again

Answer 40

I'm in safe mode right now, so I'm experiencing zero lag

Answer 41

And I have sound enabled in safe mode too

Answer 42

So I can listen to music while I'm on the net

Answer 43

what is safe mode

Answer 44

Safe mode is a reduced configuration mode that is normally used for troubleshooting purposes. But once they created the a way to enable the network while in safe mode, I started noticing how much better my computer functions in safe mode. There are a lot of services running in the background on your computer when it is in normal mode, cause your computer to function inefficiently. But it safe mode, those services are turned off and only the minimum necessary services run, so your computer functions like new.

Answer 45

i gotta restart the computer and then there are wierd settings for my computer

Answer 46

There are still a few things you would have to set before running safe mode. The only thing is, Microsoft Office will not run in safe mode. Skype and most other programs will still run in safe mode.

Answer 47

oh

Answer 48

Once I figure out a way to run Microsoft Office in safe mode, I will never need normal mode ever again.

Answer 49

I gotta get back to work otherwise I will never finish
