    the single ' means arc minutes, usually just called minutes, meaning 1/60 of a degree See http://zonalandeducation.com/mmts/trigonometryRealms/degMinSec/degMinSec.htm 30' means 30/60 of a degree or 0.5 degrees 7º 30' = 7.5º

    This should help tanx=2tan(x/2) /(1-tan^2(x/2) ) So, |dw:1358674326162:dw|
