Question

i need help with locus does any one know how to find the ewuation of them

Answer 1

locus or focus?

Answer 2

I'm assuming you're talking about a locus of point, i.e if you move a point the shape formed.

Answer 3

yeah thats what i am talking about

Answer 4

I know a little about them. Usually I try to graph them and then use the graph to write the equation.

Answer 5

sounds like topology

Answer 6

It's a mix of topology and geometry

Answer 7

yeah but i have a given and i need to ind the equation of it

Answer 8

What's the given?

Answer 9

line m
and then the condition is a set distance r from line m

Answer 10

The locus of point for that should be two lines, one on either side of line m (unless you are in three space, then it's an open cylinder with radius r).

Answer 11

In fact I would assume you are in three space if you are discussing a locus of points so you should have an open cylinder of infinite height and radius r.

Answer 12

i am doing it of 2 lines but that waht they give me

Answer 13

If you want two lines then they are parallel to m so they will have the same slope and if you use the distance formula you can find points on the other two lines and use those to write the equations.

Answer 14

ok
