... Example 3.5. Isometries of the plane (congruences) which fix the origin are linear maps. Examples include reflection across an axis that passes through the origin and rotation by a prescribed angle θ about the origin. Exercise 3.6. Prove that every congruence of the plane fixing the origin is either ...

VECTORS 1. Introduction A vector is a quantity that has both
... A vector is a quantity that has both magnitude and direction. This is in contrast to a (more familiar) scalar, which has only magnitude. Vectors are important as many quantities are direction-dependent; examples of vectors which you may have encountered include force, velocity and electric field. He ...

... instead the C-span of it). Now, each CKgH ⊗ W is just CK · (gH ⊗ W ). Note that gH ⊗ W = g ⊗ W is a vector space since gh1 ⊗ w1 + gh2 ⊗ w2 = g ⊗ (h1 w1 + h2 w2 ). We can identify it with W by mapping gh ⊗ w 7→ hw. Moreover, both CK and gH ⊗ W are representations of Hg := K ∩ gHg −1 . We denote by Wg ...

Two n×n matrices are similar if and only if they represent the same linear operator on Rn with respect to different bases. Theorem If A and B are similar matrices then they have the same (i) determinant, (ii) trace = the su ...
