Initial and terminal points of the vector [tex]\vec{PQ}[/tex] of (3., 3) and (5, 7) , and the initial and final point of the vector [tex]\vec{RS}[/tex] of (4, -5), and (1, -5), indicate that the the difference between the vectors is; 5·i + 5·j
A vector is a quantity that has both magnitude and direction.
The specified vectors are;
The initial and terminal point on vector [tex]\vec{PQ}[/tex] are; (3, 3) and (5, 7)
The initial and terminal point of vector [tex]\vec{RS}[/tex] are (4, -6), and (1, -5)
Therefore, the vector [tex]\vec{PQ}[/tex] - [tex]\vec{RS}[/tex] is therefore;
The vector form of [tex]\vec{PQ}[/tex] = <5 - 3, 7 - 3> = <2, 4>
The vecror form of [tex]\vec{RS}[/tex] = <1-4, -5 - (-6)> = <-3, -1>
The difference between the vectors is therefore;
The vectors are therefore;
[tex]\vec{PQ}[/tex] = 2·i + 4·j
[tex]\vec{RS}[/tex] = -3·i - j
The difference between the vectors is therefore;
[tex]\vec{PQ}[/tex] - [tex]\vec{RS}[/tex] = (2 - (-3))·i + (4 - (-1))·j = 5·i + 5·j
