Can someone solve this so I can get a direct equation for Cohen's d? #statspic.twitter.com/IlJzWVOGLc

aaaah, okay! Now I see. I actually think that the multiple line solution is neater, don't think you can simplify much
Oh well. I'm not particularly good with algebra, so I'm not the right person ti ask to rearrange stuff without errors! :) @dingding_peng

If you're good, maybe you can solve this one! :) http://emilkirkegaard.dk/en/?p=6570 It's something with infinite series that converge

I tend to solve everything using WolframAlpha, not sure whether that qualifies as a skill...

Don't think WA works for this one. Basically have to show (5) from (1-4). Empirically, it works out (when n = large).
