Dec 18	reviewed	Looks Good Finding probability P(X<Y)
Dec 18	reviewed	Looks Good What's wrong with this spectrum of a “scalar product” in $l^2$?
Dec 18	reviewed	Looks Good calculate the period of an hypotrochoid
Dec 18	comment	calculate the period of an hypotrochoid What is $a$ and what is $b$?
Dec 18	comment	calculate the period of an hypotrochoid Could you please put a definition of a hypotrochoid into your question? I am sure that will get you answers.
Dec 18	reviewed	Reviewed Problem with finding critical point of trig function
Dec 18	reviewed	Reviewed Why for a compact metric probability space, any Borel subset can be approximated by compact set?
Dec 18	reviewed	Reviewed Is the limsup of a sequence of measures also a measure?
Dec 18	reviewed	Reviewed Problem with finding critical point of trig function
Dec 17	comment	Can't argue with success? Looking for “bad math” that “gets away with it” That's a standard method to prove polynomial identities by proving them for enough special values.
Dec 17	comment	Can't argue with success? Looking for “bad math” that “gets away with it” These are not very good examples, because they actually can be (and are being) used reliably. (As opposed to cancelling digits, say.)

Dec 14	reviewed	Looks Good Possible rational canonical forms a matrix
Dec 14	reviewed	Approve suggested edit on Is the square for a number $n\in \mathbb{Z}$ even, then is also $n$ even - prove this via contraposition?
Dec 14	reviewed	Approve suggested edit on How many fractional digits do I need to represent a number of base $m$ in base $n$?
Dec 14	reviewed	Leave Open Integral as an invariant of non-linear transformation
Dec 14	reviewed	Leave Open Matrix P to the power of 4, i.e $P^4$, is this the same as $P^2 \cdot P^2$?
Dec 14	reviewed	Approve suggested edit on verify k-form is exact
