    Need your help mates!

    okay i've started self-studying physics and i see i've got to learn loads of maths. so i was looking for a book for an all-round intro to the maths i'm going to need right after one-variable...

    n!=n(n-1)! => 1!=1*0! but 1!=1 so 0!=1

    n!=n(n-1)!
    => 1!=1*0!
    but 1!=1
    so 0!=1
  7. angular momentum for objects whose angular motion isn't exactly circular(elliptical I mean)

    L^2=v^2*r^2(per unit mass)
    v^2=ds^2/dt^2=dr^2/dt^2+r^2*dΘ^2/dt^2(in polar coords)
    L^2=r^2* (dr^2/dt^2+r^2*dΘ^2/dt^2)
    am I right? if so, is this eqn. applicable to planetary motion in Newtonian...

    E^2=(pc)^2+(mc^2)^2 this is the full equation.
    when m=0 (e.g. photons,gluons etc.), it minimizes to E=pc
