For 1921, determine the inner product of the given vectors using (a) the inner product (5.1.14) in 18, (b) the standard inner product in R2.v = (1, 2), w = (2, 1).

Section 1.1 Introduction Linear Equation General form is ax +a+++=ax a.x b 11 2 2 33 nn where the a's ari constant, x's aie variables and b is a constant. In short, a linear equation contains • no products of variables, • no functions of variables and • no powers of variables (other than the first power) Examples: Is the equation Linear or Nonlinear 3sin x+2= 5 (A) 236x−=+ (B) 1 2 1 2 π 0 3n (C) i=++2s()2 x1 4 xx += 30 (D) 12 2 π 1 (E)os x1 2 3xx 3 34 3x4+z=− π 2 (F) A System of Linear Equations contains one o
