Geometric Series
I realize geometric series isn't exactly probability, but attracts the mathematically-inclined posters, so here goes. I also posted in the SMP forum.
I need to show that: 2*sum[ (( 1/3)^t) * cos(wt) ] where we are summing from t=1 to inf, is equal to: ( 1 - 3cos(w) ) / ( 3cos(w) - 5 ) Any links/tips would be helpful. I haven't been able to find anything via google. |
