After doing nearly all the coursework for a Ph.D. in math, I then did all the coursework for a Ph.D. in statistics and completed that degree.

You are obviously using degrees where you need to use radians.

@BrianM.Scott : So if you needed such a term and if none is on the shelf, so you need to coin it yourself, what would you use? $\qquad$

comment How to deal with a nosy fellow graduate student?
Possibly he's simply desperate to do something right and feels that imitating you in what you read is his only hope of succeeding.

comment Linear independent set of functionals makes certain map surjective
If you write \lambda\text{ker}\Lambda you see $\lambda\text{ker}\Lambda$ but if you write \lambda\ker\Lambda you see $\lambda\ker\Lambda$, with proper spacing before and after "ker". Proper spacing includes the fact that in $\lambda\ker(\Lambda)$ there shouldn't be as much space after "ker" as if the left parenthesis were not there. Using \ker in that way is standard usage. I changed it to \ker. $\qquad$

comment A question an normal to the circle
I'd say "perpendicular to the line" rather than "perpendicular to the slope of the line". $\qquad$

comment A question an normal to the circle
"by definition" is wrong. The fact that the lines normal to the circle are precisely those that pass through the center is a demonstrable proposition, not a definition. $\qquad$
