The Split command splits the range of integration of v: .

The second parameter c is a splitting point or a list of splitting points. Alternatively, a list of the form [f(i), i = m..n] can be specified. In this case [seq(f(i), i=m..n)] will be used as the splitting points if m and n are constants.  If at least one of m or n is symbolic, the points f(m), f(m+1), ... , f(n-1), f(n) will be used and the result is correct as long as (m-n) is an integer.
