Title: "Show that..." questions
Post by: dekoyl on September 06, 2009, 05:51:20 pm: I think the "show that $x=....$ " questions are quite common.
Do we write " $x=....$ " as required" at the end, or "... QED" or just leave it blank?

Thanks.

So we can just write " $x= \sqrt{2x} \square$ or $\blacksquare$ " ? Haha.
