V(X) measures the variation in the first half and V(Y) measures the variation in the second half What is missing is a measure of the variation between the first half and the second half There is such a measure, it is called the covariance of X and Y and written Cov(X,Y) The correct statement about V(X Y) is Var(X Y) = V(X) V(Y) 2 Cov(X,Y). 1 v 2 2X and cv 1 v 2 2Y, and in particular cv 1 v 2 2X\Y Thus X\Y satis es the subspace property, and by Proposition 23 in the notes, it is a subspace For X Y, we observe that given any v 1;v 2 2X Y and c2K, there exist x 1;x 2 2X and y 1;y 2 2Y such that v 1 = x 1 y 1 and v 2 = x 2 y 2 (This is from the de nition of the sum of.

U;V(u;v) dv To work out the integral, we split it up into two cases depending on whether uis less than 1 or not If u is less than 1, then maxfu;1g= 1, so 1 is the lower limit Otherwise, maxfu;1g= u, so uis the lower limit Thus, if 0 <u<1, then f U(u) = Z 1 1 1 v3 dv= 1 2 v 2 1 1 = 1 2 If u 1, then f U(u) = Z 1 u 1 v3 dv= 1 2 v 2 1 u = 1 2u2.

May 26, Basically, start with the range of \(u\)’s and “build up” the equation for the side and we get the range of \(v\)’s for this side So, we now know how to get ranges of \(u\) and/or \(v\) for new equations under a transformation However, this is not something that is done terribly often but it is a useful skill to have in case it does.
