Help

fresh estuary May 2, 2023, 5:44 PM

#

ok so

#

if these two things intersect along a line

#

you could maybe just find 2 points on the intersection

#

and just draw the line @ember bloom

ember bloom May 2, 2023, 5:48 PM

#

draw a 3d line?

fresh estuary May 2, 2023, 5:48 PM

#

you dont need to draw it

ember bloom May 2, 2023, 5:49 PM

#

i think its a 3 way prism

fresh estuary May 2, 2023, 5:49 PM

#

its not

ember bloom May 2, 2023, 5:49 PM

#

oh

loud fern May 2, 2023, 5:50 PM

#

Long day

minor crane May 2, 2023, 5:52 PM

#

do cross product to find parallel vector

#

idk how to find a point on the line though

fresh estuary May 2, 2023, 5:53 PM

#

you can like

#

just choose x=1

#

and then you have sim equations!

minor crane May 2, 2023, 5:53 PM

#

can you choose any value

#

for x,y,z

ember bloom May 2, 2023, 5:53 PM

#

i thought cross finds normal

fresh estuary May 2, 2023, 5:54 PM

#

yeah

minor crane May 2, 2023, 5:54 PM

#

it will find a normal to where the two normals meet

#

which is parallel to the line of intersection

ember bloom May 2, 2023, 5:54 PM

#

oh and will that be parallel

minor crane May 2, 2023, 5:54 PM

#

yeah

ember bloom May 2, 2023, 5:54 PM

#

oh

minor crane May 2, 2023, 5:58 PM

#

but if i let x=1, I wont get what they want, which is x=4, so do I need to look at what they want and choose that, so in this case, x=4 or y= 3 or z=1

minor crane May 2, 2023, 5:59 PM

#

fresh estuary yeah

but in a question to find a line of intersection without being a show that, I can sub in any value of x,y,z

fresh estuary May 2, 2023, 6:00 PM

#

yep

#

usually its a safe bet to not choose 0 tho

#

cuz sometimes 0 fucks it a bit

minor crane May 2, 2023, 6:00 PM

#

in a paper i did the other day, x=0 worked

#

#

There

ember bloom May 2, 2023, 6:05 PM

#

is that the solutio

loud fern May 2, 2023, 8:03 PM

#

Yh

ember bloom May 2, 2023, 8:05 PM

#

thanks!

#

minor crane

doing cross product that way is criminal

#

i j k should be vertical fr

minor crane May 2, 2023, 8:25 PM

#

Whaaytttyy, it’s always at the top vertical

fresh estuary May 2, 2023, 10:17 PM

#

unreal jasper i j k should be vertical fr

What? Are you insane??

faint vault May 2, 2023, 10:56 PM

#

I don’t know why you’d need the cross product

#

lit just make them all vector equations and show a general point on the line lies on both planes

#

as they share a line it means by force they have an intersection along that line

unreal jasper May 3, 2023, 2:28 AM

#

fresh estuary What? Are you insane??

NO ITS NORMAL

3 v 1

waxen abyss May 3, 2023, 2:29 PM

#

minor crane

Why x = 4

minor crane May 3, 2023, 3:00 PM

#

It’s just one of the numbers they want in the answer. If it wasn’t a show that q, I would’ve used any number
