Thank you We sneak and here's your shmoop too sure

brought to you by arrows When we were in the
- 00:08
second grade no one told us that drawing arrows would
- 00:10
be a part of math On second thought maybe it's
- 00:12
because they didn't want us playing with sharp things I

have something to check out the following diagram right here
- 00:18
What is the resulting vector If the two vectors above
- 00:22
are added adding vectors and hear the potential answer to
- 00:27
this Yeah Okay Well adding vector diagrams like these might
- 00:33
look intimidating at first After all how do we add
- 00:36
an arrow to another arrow Well but it's easier than
- 00:40
it looked We just place the vectors tip to tail
- 00:43
and draw a line to complete the shape All right
- 00:46
looks like this And even if we were to set
- 00:48
up our diagram differently with vector two on the bottom
- 00:51
the answer would be the same that's Because like any
- 00:54
other edition problem a plus b is equal to b
- 00:57
plus eh So no matter what order we put him
- 00:59
in when we adam up the total vector will be
- 01:02
the same So the correct answer is c maybe mrs
- 01:05
williams should have told us about vectors to We would
- 01:07
have understood what she was talking about back then but
- 01:09
at least would have been getting yelled at for eating 00:01:12.109 --> [endTime] paste
