Combination

AI Thread Summary

There are 10 total stations between city A and city B, including both endpoints. To determine the number of types of tickets needed for passengers to commute between stations, the calculation involves using combinations. The formula applied is 2 times the combination of 10 stations taken 2 at a time, resulting in 90 types of tickets. This approach appears to be correct for enabling travel between any two stations. The solution is confirmed as valid by the original poster.

Homework Statement

There r 8 Stations between city A & city B. What is the number of types of tickets to be printed So as to enable a city passenger to commute from one place to another?

Homework Equations

The Attempt at a Solution

Total number of Stations=10
Types of tickets=2*[C(10,2)]
=90
Does it seem ok to u?

Thread 'Finding the number of ways to arrange identical balls in a circle (3 different colors)'

I tried to combine those 2 formulas but it didn't work. I tried using another case where there are 2 red balls and 2 blue balls only so when combining the formula I got ##\frac{(4-1)!}{2!2!}=\frac{3}{2}## which does not make sense. Is there any formula to calculate cyclic permutation of identical objects or I have to do it by listing all the possibilities? Thanks

Thread 'Making the denominator of a certain fraction real'

Essentially I just have this problem that I'm stuck on, on a sheet about complex numbers: Show that, for ##|r|<1,## $$1+r\cos(x)+r^2\cos(2x)+r^3\cos(3x)...=\frac{1-r\cos(x)}{1-2r\cos(x)+r^2}$$ My first thought was to express it as a geometric series, where the real part of the sum of the series would be the series you see above: $$1+re^{ix}+r^2e^{2ix}+r^3e^{3ix}...$$ The sum of this series is just: $$\frac{(re^{ix})^n-1}{re^{ix} - 1}$$ I'm having some trouble trying to figure out what to...
