ok

which part you need help

[tall cradle]

a

[lethal geyser]

ok

there is 2 way

ways i will do it

using the formula

or using vector method

which one you prefer

[tall cradle]

i understand the concept behind it

[lethal geyser]

that is good

[tall cradle]

i didnt try the formula method

or vector product jsut dot

[lethal geyser]

ok

[tall cradle]

my problem was that i couldn't cancel out the k to get a specific distance

[lethal geyser]

part a is in terms of k @tall cradle right?

[tall cradle]

nah that was the trouble

well atleast the guy who put the question in earlier said it wasnt

i tried messaging him for ms but he didnt come back

[lethal geyser]

is not in terms of k?

[lethal geyser]

they would have given you a shortest distance at least to find K

im gonna see part b

[tall cradle]

ok

[lethal geyser]

we gonna use this

[tall cradle]

ok

[lethal geyser]

@tall cradle is this the answer?

if so i can explain it to you

[tall cradle]

i dont know cos the guy gave the didnt say 😂

but yeye 100% explain

please

did you find a value for k or did it cancel out?

[lethal geyser]

i used the 3x3 matrix

determinate method

instead of doing the long methid

method of cross and dot product

[lethal geyser]
