Question

PARAMETRIC CONICS APPLICATIONS HELP :(

Answer 1

ack i used to know this
want a guess?

Answer 2

actually we don't need to guess, we can put \[r^2=x^2+y^2\] i think

Answer 3

oops spoke too soon as usual

Answer 4

is it Q.9 on P.8 of this - http://lhsblogs.typepad.com/files/parametric-packet.pdf ?

If so, then on P.19 it mentions about using calculator to find the minimum distance.

Otherwise trying to solve this by differentiation the distance wrt T; then finding the minimum will be quite a pain...just thought i wuld point it out here.

good luck :)

Answer 5

hmmm...any reason why not using the calculator function mentioned? seems like if it says u can use it, then u should :)

Answer 6

i could be wrong n there are many ppl smarter than me on OS but it would seem like a real pain to solve this analytically...just my 2-cent...

Answer 7

again just my opinion here:

post the Q in its original form w/ details on the calculator functions to be used; then see if any1 can help u w/ setting it up on the calculator.

i dont think u will get any help posting it as it is here now but its ur choice :)
