Integral of dt

  1. Nov 16, 2008 #1
    Why is the integral of dt = t + C1

    Can someone explain that to me?

    It seem the integral you are interested in is the indefinite type. So you are looking for some function f so that
    clearly f=t is one such function, but there are others
    what if we are intersted in g so that dg=0
    but for any c c*dg=c*0=0 also
    but also

    so if du=dv
    we can say
    but we cannot conclude u=v
    since d(u-v)=0
    we can conclude
    u-v=c for some c

    so if df=dt
