Find an equation of the plane consisting of all points that are equidistant from (1, 3, -4) and (2, -3, 1), and having 1 as the coefficient of x
last one i swear
find the vector between the 2 points and the distance/2
distance is subtract and pythag (1, 3, -4) -(2, -3, 1) ----------- -1 6 -5 ; sqrt(1+36+25) = sqrt(62) right?
and the subtracted part is the vector for the normal we can use
<1,-6, 5> = normal vector to find a midpoint ... add the points and divide by 2 lol
how u retain all this information truly remarkable
(1, 3, -4) (2, -3, 1) ----------- (3 , 0 ,-3)/2
we use this point and the normal ... thatll get us all we need :)
how do i set this equal to 0 then?
1(x-(3/2))-6(y-0)+5(z-(-3/2))=0
u happen to know how to determine a point of intersection given two lines?
|dw:1316573138974:dw|
i can recall some of it :) you have to parametric them and change the scalar to see if they cross
the best view i got is that vectors/lines in space can move past each other and never touch; like a floor line and a ceiling line
so to see where they are at any given time we change the scalar for the parametrics and equate them
