WebMath 122, Solution Set No. 5 1 5.2.13 (a) (⇒) if x is on l, then glide reflection acts on points on l as a translation; therefore, x,m(x) and m2(x) lie on l and are colinear. (⇐) If x is not on l, then the line joining x to m(x) crosses l (because m is a glide reflection) and so does the line from m(x) to m2(x). If these points are ... WebMath 122 Notes 6 Example 1.4.

Web(b) Let G = GL 2(R) and consider the matrices A = 0 2 1 2 0 and B = 0 3 3 0Then we have A2 = B2 = I, that is, A and B have order 2, which is finite. However, AB = 2/3 0 0 3/2 which has the startling property that (AB)n = (2/3)n 0 0 (3/2)n which is never equal to the identity for n 6= 0, i.e. AB has infinite order. ♦ WebMATH 122 at Harrisburg Area Community College, Lancaster (HACC Lancaster) in Lancaster, Pennsylvania.

The zero matrix is symmetric, and the set is closed under addition and scalar multiplication because for symmetric matrices A,B and c ∈ F, (A + B)t = At + Bt = A + B and (cA) t= cA = cA. (b) The zero matrix is not invertible, hence this is not a subspace. (c) This is a subspace.
