Where is the 3/4 coming from?

restive harness Oct 20, 2023, 5:34 PM

#

when trying to find AB you can do 3/4(AB) or 1/3(AB)

#

Do u mean AX?

restive harness Oct 20, 2023, 5:34 PM

#

but using 3/4(AB) gives the wrong ans

#

oh yeah

#

AX

#

ty

mighty thistle Oct 20, 2023, 5:35 PM

#

Ye AX is 3/4(b-a)

#

How can we get XM

restive harness Oct 20, 2023, 5:35 PM

#

on the working above it says 1/4(b-a) tho

mighty thistle Oct 20, 2023, 5:36 PM

#

Cos u dont need AX to get XM

restive harness Oct 20, 2023, 5:37 PM

#

then what do you do?

mighty thistle Oct 20, 2023, 5:37 PM

#

Whats the simplest path to get to M from X

restive harness Oct 20, 2023, 5:39 PM

#

3/4(AB)+1/2(BC) so 3/4(-a+b)+1/2(a)?

#

What vector is 3/4(AB)?

restive harness Oct 20, 2023, 5:39 PM

#

3/4(-a+b)

mighty thistle Oct 20, 2023, 5:40 PM

#

I mean which one does it represent

restive harness Oct 20, 2023, 5:40 PM

#

AX

mighty thistle Oct 20, 2023, 5:41 PM

#

In terms of the big letters whats the quickest way to go from X to M

restive harness Oct 20, 2023, 5:41 PM

#

From 3/4AB to 1/2BC

#

1/4BA and 1/2BM?

#

but they are the same thing i dont see an issue with using either

#

one gives the wrong ans and the other gives the correct ans

#

What is 3/4AB in big letter

restive harness Oct 20, 2023, 5:44 PM
