don't they have the same expected waiting times?

comment Existence of Linear Transformation between 3D line and 2D line
@AndyYao yes, you take one of the end points (start there when $t=0$) and when $t=1$ you should end up on the other end point... After you have the parameterization done, your segment become a transformation of $[0,1]$, over which $t$ is defined. Can you then given a point on your segment, produce the corresponding value of $t$, which you can map to the second segment.

comment Representing any number in $R_+$ by means of two numbers
Looks like fixing $a,b$ and letting $n,m$ vary

comment Representing any number in $R_+$ by means of two numbers
So for a simple example, how would you approximate $\sqrt{2}$ with $b=e$ and $a = 1/\pi$?

Yes, just parameterize both of them...

comment Find Linear Transformation Given Set of Vertex
@user2566092 indeed, you are geometric and i am algbraic :) -- i guess it more of a question of how far to spell things out. I am happy to see others hint as well without giving away the result so the OP doesn't do any work at all...

comment How to find that the alternating sum converges
isn't $a_{i(i+1)} = a_{(i+1)i}$?
