I suggest making one out of paper and labelling highlighting the dimensions that
you know or can derive. This experiment will be very fun. If you don't have
a protractor, you can use a watch or clock and the 160 degrees is approximately
from 3.333333 minutes to 30 minutes using the arc of a minute hand. | {"url":"http://www.mathisfunforum.com/viewtopic.php?pid=28293","timestamp":"2014-04-19T05:00:00Z","content_type":null,"content_length":"11924","record_id":"<urn:uuid:2b794722-f1c6-4f1b-bdfe-19de412cac00>","cc-path":"CC-MAIN-2014-15/segments/1397609535775.35/warc/CC-MAIN-20140416005215-00641-ip-10-147-4-33.ec2.internal.... |

I think my questions relates to this other: "counterexamples to differentiation under integral sign"
In fact, it provides a counterexample

Is a semicontinuous real function Borel measurable?

Let $f(x,u): [0,1]^2 \mapsto \mathbb{R}$ be a continuous function.
[Q] Is $g(x) = \inf_{u\in [0,1]} f(x,u)$ always Borel measurable? If not, can one find a counter-example?
