Question

I have a problem where I must find the Cartesian equation for:
x=t^2
y=4+3t
into
x=Ay^2+By+C
I have found C, but need help in finding the values for A and B

Answer 1

it seems you are either missing some info here or im a bit more rusty on geometry than i thought, how exactly did you find C?

Answer 2

I came up with t^2=A(4+3t)^2+B(4+3t)+C

Answer 3

but i'm still kind of confused as to how I even got it ha

Answer 4

it's the correct problem i checked

Answer 5

yeah, you have 3 variables there and no way to eliminate any of them, so unless your proff gave you some format to put it into and then from that you know the points your trying to find?

Answer 6

i mean the way to eliminate them is to use the t value
and then deal with that bottom equation

Answer 7

so lik eeither put everything in terms of x or y

Answer 8

right but you can only ever solve the variables in terms of the other variables, meaning you can find A as a function of B and C, B(A,C) and C(A,B)

Answer 9

yes i know
that's why i need to find a way
out by plugging in constants on both sides of the equation
that make A or B go to zero in order to solve for the variables

Answer 10

ahh, right. and then you just do the same thing to find A and B i think, set the ones your not finding to 0

Answer 11

see i don't know how to do the rest
i'm really cracked out and can't thinka nymore ha

Answer 12

honestly you should confinr that with someone else too though, its been a while since iv done a problem like this

Answer 13

if your finding A you just set B and C to 0 because they are intercepts, right?

Answer 14

well i'll know if it's right because i have to type my answers into a computer system that will tell me if it's correct or not

Answer 15

unlimited trials

Answer 16

here we go: http://www.personal.kent.edu/~rmuhamma/Algorithms/MyAlgorithms/parabola.htm

Answer 17

so you have a polynomial function of the 2nd degree which is a quadradic

Answer 18

ok

Answer 19

question where do u go to school?

Answer 20

this is a trickey little bastard, you have to change the form of the original equation. see

If b = 0, the quadratic function has the form f(x) = ax2 + c.

so what i think you have to do, is noting those derived equations and plugging in 0 to the other variables you get some new equations which then allow you to solve for the others by plugging them into eachother. lemme keep reading

Answer 21

ughhh it sucks!! i haven't slept in two days fml

Answer 22

lol its been too long, i dont understand what that website is saying...

Answer 39

i am too, it's just too weird

Answer 40

what do you major in ?

Answer 41

computer engineering technology, you?

Answer 42

ha sounds intense, i'm doing business econ and psych

Answer 43

haha im concentrating in psych, too weird

Answer 44

haha oh the weird realms of the internet

Answer 45

its got to be less coincidental than were making it out to be. were in a pretty tech-savvy part of the english speaking world. but still thats the whole northern east coast...

Answer 46

how did you find this site?

Answer 47

haha idk i was just wearching for help things and it came up

Answer 48

why do you help random people with math?

Answer 49

honestly i dont really know

Answer 50

i kinda stumbled here like 2 days ago and got a kick out of helping people out with their math, most of the stuff on here is low level calc or easier so its not so bad

Answer 51

guess i got sick of facebook and this was another way to procrastinate?

Answer 52

i guess that's not a bad way to procrastinate, bettering the world's math skills

Answer 53

haha, yeah doing other people's homework is fun but doing my own is agonizing, go figure

Answer 54

ha

Answer 55

what class is your parabola thinger from? i dont remember having to do this stuff

Answer 56

third semester of calc

Answer 57

shows how much i learned in calc...

Answer 58

but it's something i learned a long time ago, i just don't remember it

Answer 59

don't worry though, i have the rochester minions working on it

Answer 60

the rochester minions eigh?

Answer 61

yes

Answer 62

you should prolly let me know how to go about contacting these minions. could be helpful for diff eq

Answer 63

haha, you literally just walk around u of r campus, they're around, sometimes you have to look in the stacks or the depths of the librar but there's always a guarantee you'll find one

Answer 64

haha, even at 2 am. that seems sketchy, especially the library part, whats a library?

Answer 65

the minions are having trouble with it too, darn

Answer 66

tell your professor that its impossible. ill see if my roomate knows how to do it

Answer 67

ok it's just it's due tomorrow morning at 6am
ick

Answer 68

haha people keep looking at this question and then leaving

Answer 69

theres 3 rit kids in here working on your silly parabola

Answer 70

you said you have infinite number of trys?

Answer 71

\[y=4+3\sqrt{x}\]

Answer 72

give that a go

Answer 73

i'll try it

Answer 74

idk how long this website will wokrk though, its slowing my comp down a lot

Answer 75

i got A it's 1/9, idk if that will help find B

Answer 76

lol i have no idea how you got that or what it means. anyways im going to go sleep or eat or something, facebook me (Tim Heebs) you should come to some parties and bring friends. god knows RIT needs help with the ratio at parties haha

Answer 77

haha yea, your name already showed up when i was worried about the problem, and yea us girls here sometimes want to go to some RIT parties, that would be cool

Answer 78

sounds good, ttyl then. good luck with your calc
