 Posted: Tue Feb 08, 2011 11:06 am    Post subject: Interval notation and Piecewise defined functions I would like to present interval notation in openoffice math such as x in (- infty, -5] union [5, infty) However, because the brackets do not match, this is not allowed. I Is there any workaround? This situation also might come up in piecewise defined functions, f(x) = left lbrace matrix{x^2+1, # x<0 ## x - 1, # x>=0} right rbrace I would like to find a way to show only the left brace, but not the one on the right.
