Problem Solving using 3D Vectors Problem-solving with 3-D vectors 3-D vector problems can be solved using the same principles as 2-D vector problems (see Problem Solving using Vectors) Vectors can ...
Vectors in 3 Dimensions What is a 3-D vector? Vectors represent a movement of a certain magnitude (size) in a given directionYou should have already come across (2D) vectors at AS (see Basic Vector...
Problem Solving using Vectors Problem-solving with vectors Vectors can be used to prove two lines are parallel (see Vector Addition) They can also be used to show points are collinear (lie on the s...
Position Vectors What is a position vector? Position vectors describe the position of a point in relation to the origin They are different to direction vectors which describe the direction and dist...
Vector Addition Vector addition Adding vectors together lets us describes the movement between two points The single vector this creates is called the resultant vector Subtracting a vector is the s...
Magnitude & Direction What is the magnitude of a vector? The magnitude of a vector is simply its size It also tells us the distance between two points You can find the magnitude of a vector usi...
Basic Vectors What is a vector? Vectors represent a movement of a certain magnitude (size) in a given direction You should have already come across vectors when translating functions of graphs They...
