If we think of W 1 as the number of trials we have to make to get the first success, and then W 2 the number of further trials to the second success, and so on, we can see that X = W 1 W 2 W r, and that the W i are independent and geometric random variables So EX = r/p, and Var(X) = r(1−p)/p2 5 Poisson random variables.

We now have the tools I think to understand the idea of a linear subspace of RN let me write that down then I'll just write it just I'll just always call it a subspace of RN everything we're doing is linear subspace subspace of our n I'm going to make a definition here I'm going to say that a set of vectors V so V is some subset of vectors subset some subset of RN RN so we already said RN when.

Our problem is the upper boundary curve xy = 1 To change this to u −v coordinates, we follow Method 1 u = x2 −y2 ˆ.

R r Figure31 Until now we’ve thought of a linear transformation as an expression combining nvariables to produce a vector in Rm If we limit ourselves to this algebraic viewpoint we miss a fuller appreciation of linear transformations For example, consider the mapping that rotates the points in the plane through an angle θ about the origin.
