Whats the question?

OpenStudy (anonymous):

oh nvm

OpenStudy (raymonde20):

Its the second or first.

OpenStudy (anonymous):

I think its the 1st or 4th let me see

OpenStudy (anonymous):

I was more looking for a step by step typa thing

OpenStudy (anonymous):

so do you know what the things in parenthesis represent? the entire thing?

OpenStudy (anonymous):

not in parenthesis sorry, i mean the fractions what do they represent?

OpenStudy (anonymous):

it starts with an s

OpenStudy (anonymous):

u there?

OpenStudy (anonymous):

ok so they represent slope

OpenStudy (anonymous):

Okay

OpenStudy (anonymous):

ok so what is the slope of a line in relation to the slope of another line perpendicular to it

OpenStudy (anonymous):

I honestly don't know

OpenStudy (raymonde20):

@msasu25 She needs to learn..

OpenStudy (anonymous):

There’s a nice approach to this problem that uses vector cross products. Define the 2-dimensional vector cross product v × w to be vx wy − vy wx (this is the magnitude of the 3-dimensional cross product). Suppose the two line segments run from p to p + r and from q to q + s. Then any point on the first line is representable as p + t r (for a scalar parameter t) and any point on the second line as q + u s (for a scalar parameter u).

OpenStudy (anonymous):

if 2 lines are perpendicular one has slope m and the other has slope -1/m

Spambot Activated

OpenStudy (raymonde20):

lol

OpenStudy (raymonde20):

lol

OpenStudy (raymonde20):

lol

OpenStudy (raymonde20):

lol

OpenStudy (raymonde20):

lol

OpenStudy (anonymous):

Okay and m stabnds for slope?

OpenStudy (raymonde20):

lol

OpenStudy (raymonde20):

lol

OpenStudy (raymonde20):

Spambot Deactivated

OpenStudy (anonymous):

@raymonde20 please stop

OpenStudy (anonymous):

yes anything can stand for slope but conventionally m stand for slope,

OpenStudy (anonymous):

Okay so whats next

OpenStudy (anonymous):

ok so next thing i would do is draw it out

OpenStudy (raymonde20):

lol

OpenStudy (raymonde20):

lol

OpenStudy (raymonde20):

lol

OpenStudy (raymonde20):

lol

OpenStudy (raymonde20):

lolo

OpenStudy (raymonde20):

o

OpenStudy (raymonde20):

l

OpenStudy (raymonde20):

l

OpenStudy (anonymous):

reported u dude

OpenStudy (raymonde20):

l

OpenStudy (raymonde20):

l

OpenStudy (anonymous):

reported

OpenStudy (anonymous):

ok so lets draw it out, u wanna try first?

OpenStudy (raymonde20):

Idc.

OpenStudy (anonymous):

bro get a life, peace

OpenStudy (raymonde20):

FUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU

OpenStudy (anonymous):

do you want to draw it or no?

OpenStudy (raymonde20):

No

OpenStudy (raymonde20):

xD

OpenStudy (anonymous):

Could you draw it?

OpenStudy (anonymous):

sure

OpenStudy (anonymous):

Raymond stop i reported you too you took it too far by saying "fu"

OpenStudy (raymonde20):

FUUUUU

OpenStudy (raymonde20):

FU

OpenStudy (raymonde20):

fu

OpenStudy (raymonde20):

fu

OpenStudy (raymonde20):

fu
