explain what the third parameter does? Both example have 0 as the third
parameter. I've seen other things used for the third parameter, but it is not
explained! Help!
Define this function as:
g(x) := when(x<pi, 4*sin(x), 0) + when(x>=pi and x<0, 2x+6, 0) +
when(x>=0, 6.1x^2, 0) + when(x>6, undef, 0)
