Question

amistre64 · Answer

subtract the vector from teh point

amistre64 · Answer

2,0

-----
(1,-2)

anonymous · Answer

I got confused with the A(2,0) what's the A for

amistre64 · Answer

A just names the point.... this point is called A and it is defined as (2,0)

anonymous · Answer

How would you do it for initial of A(1,1) and u = (1,2)?

amistre64 · Answer

you mean fine the terminal point from that ?

anonymous · Answer

yeah

amistre64 · Answer

initial point + vector

amistre64 · Answer

1,1

----
(2,3)

anonymous · Answer

B(2,3)

anonymous · Answer

Alright I guess the solution manual is wrong thanks

amistre64 · Answer

unless your not asking the same question as the book :)

anonymous · Answer

Nope it's find the terminal point of the vector that is equivalent to blah blah

anonymous · Answer

But yeah I think it's an error thank you though

amistre64 · Answer

a vector is just an arrow pointing in the direction of the slope..

to get from an initial point to another point; add the vector to the point

to get the other way around; subtract the vector from the point
