Vectors Flashcards
1
Q
Component Form of a Vector
A
v = (Q1 - P1,Q2 - P2)
2
Q
Magnitude of a Vector
A
||v|| = √(q1 - p1)² + (q2 - p2)²
3
Q
P = ? Q = ?
A
P = initial point Q = terminal point
4
Q
To find a unit vector, u = ?
A
u = v/||v||
5
Q
Component Form of a vector given θ
A
v = ||v||cosθi + ||v||sinθj
6
Q
Angle (θ) Between
A
θ = cos^-1[(u)(v)/(||u||)(||v||)]
7
Q
The vectors are orthogonal (perpendicular) if…
A
(f)(u) = 0
8
Q
The vectors are parallel if…
A
u = k(x,y) and v = c(x,y)
