 Nov4 comment Mathematical proof for long-term behavior of a sequence of integer vectors @F'OlaYinka if they are all given $0$, it does not work :P Nov4 comment Mathematical proof for long-term behavior of a sequence of integer vectors Interesting questions come from this, I wonder what the rate of convergence is, I assume it depends on 1) the number of child and 2) the difference between the richer and the poorer but i may be wrong Nov4 comment Mathematical proof for long-term behavior of a sequence of integer vectors @EuYu yeah I think so too. I don't know yet why it works though Nov4 comment Mathematical proof for long-term behavior of a sequence of integer vectors It may not matter, but are they given the same amount of cent? Nov3 comment How to solve $\sin(x)\frac{d}{dx}\beta \left ( x \right )+\cos(x)\beta (x)=1$? Note that you can use \sin, \cos for the $\sin,\cos$ functions. see the difference between $sin(x)$ and $\sin(x)$ Nov3 revised How to solve $\sin(x)\frac{d}{dx}\beta \left ( x \right )+\cos(x)\beta (x)=1$? Fixed latex Nov3 suggested suggested edit on How to solve $\sin(x)\frac{d}{dx}\beta \left ( x \right )+\cos(x)\beta (x)=1$? Nov3 answered Bernoulli vs. uniform distribution Nov3 answered Combinations help please Nov3 comment Combinations help please Since this is homework, have you tried anything that you could show us? Nov3 revised How many solutions does $\cos(97x)=x$ have? added 204 characters in body Nov3 revised How many solutions does $\cos(97x)=x$ have? added 414 characters in body Nov3 comment How many solutions does $\cos(97x)=x$ have? @Jonathan you are right, I should have plotted both side Nov3 revised How many solutions does $\cos(97x)=x$ have? added 33 characters in body Nov3 answered How many solutions does $\cos(97x)=x$ have? Nov3 comment Combinations: 5 seniors, 3 juniors to form committee of 5. The thing to remember is the more constraint you have on a choice to make, the more you want to make that choice first Nov3 comment Expected number of tosses to get T,T @StefanHansen Here the probability of Heads is $p$ and he looks for TT, in the other example, he looks for $HH$ for which heads has prob $p$. Substitute $q=1-p$ in the above to get what you have on the other page.
