MTH 141 Chapter Notes - Chapter 1: Parametric Equation, Scalar Multiplication, Parallelepiped
Document Summary
Standard basis any vector can be written as a sum of scalar multiples of e1 and e2. Proving a set is not in the subspace. Be in the zero subspace (trivial subspace) If a set is in the subspace = the set is called a spanning set for the subspace. Linearly dependent one of the vectors is equal to a linear combination of some of the other vectors. We can find the other vectors where there are solutions that are non-zero. Has a solution thus it is linearly dependent. Linearly independent the only solution to the equation must be 0. Basis v is a spanning set for subspace of s of r^n , v is linearly independent. Plane (linearly independent) v1, v2 and passes through p. Dot product/ scalar product / standard inner product. Scalar equation of planes/hyperplanes (sub in point into x1,x2,x3) Need a point, and normal vector, finding x1,x2,x3 ( a point on the plane)
