We can reverse the perspective by using themultiplication property of conditional probability. f X;Y (x;y) = f YjX(yjx)f X(x): Thus, we can introduce a bivariate mass function by giving the mass function for X and the conditional mass for Y given the value for X. 10/18

      Chapter 12. Transformations in 3D 2 • A rigid transformation (in the sense I have defined it) preserves angles as well as distances. That is to say, if P, Q and R are three points transformed to P∗, Q∗, and R∗, then the angle θ∗ betweensegments P∗Q∗ and P∗R∗ is the same as the angle θ between PQ and PR.This is because of the cosine law, which says ...

Then we say that f is a geometric transformation if f also maps L1 onto L2. In other words, a 1-1 transformation f : P1 →P2 is geometric if takes the set P1 of all points in G1 onto the set P2 of all points in G2, and takes the set L1 of all lines in G1 onto the

Similarly, when you perform two or more transformations that have a horizontal effect on the graph, the order of those transformations may affect the final results. The vertically-oriented transformations do not affect the horizontally-oriented transformations, and vice versa.
