Finding matrix projection and perpendicular

Principles

Steps

Proj

• Use components in given vector to create proj equation
  • coefficiennts of x1,x2 are points, rest as usual
  • Replace x with standard basis vectors, solve
  • Combine to form proj v

Perp

• Same as proj but remember to have the point - proj

Examples

• given v=(-2,1), find [proj_v] and [perp_v] ?
• proj_v
  • 
• perp_v
  • 
• Can be applied to any point to find projection/perp
  • ex)
