Topics in Vector Algebra
1
Basic Vector Concepts and Operations
- Vector: A quantity with both magnitude and direction, represented by directed line segment
- Position vector: Vector from origin O to point P, denoted as OP⃗
- Unit vector: Vector with magnitude 1, â = a⃗/|a⃗|
2
Scalar (Dot) Product of Vectors
- Dot product gives scalar result: a⃗·b⃗ = |a⃗||b⃗|cosθ
- Geometrically represents projection of one vector on another
- Dot product is commutative: a⃗·b⃗ = b⃗·a⃗
3
Vector (Cross) Product of Vectors
- Cross product gives vector result perpendicular to both original vectors
- Magnitude: |a⃗×b⃗| = |a⃗||b⃗|sinθ
- Direction given by right-hand rule
4
Scalar Triple Product and Vector Triple Product
- Scalar triple product: [a⃗ b⃗ c⃗] = a⃗·(b⃗×c⃗) gives scalar result
- Represents volume of parallelepiped formed by three vectors
- Cyclic property: [a⃗ b⃗ c⃗] = [b⃗ c⃗ a⃗] = [c⃗ a⃗ b⃗]
