Diffy-Q



In my work as a risk analyst I use probability, statistics, and calculus frequently. In my copious free time (CFT) I analyze sporting events to develop wagering strategies: more calculus.

 

Stats. I don't know if I was more or less confused by the time our prof jumbled through it. The first two months was fine, but in the end he had to hurry to finish it and didn't really teach us that much (or, at least, that well). That said, give me a stats book and I work through it fine - it's remembering things off the top of my head that tended to trip me up in that course. I did well, but I didn't learn as much (or as well) as I'd have liked.

My uncle is in risk management - he was risk manager for the capital city here, then he went to Teck-Comincos in BC, Canada, and now he's with some natural gas company heading up their risk management division. Pretty crazy stuff they run into sometimes (or have to look out for).

 

Course 415 at Ohio State, Differential Equations. I then changed majors and hardly needed 050, pre-college mathematics.

 

as a civil engr, the MOST math I will ever use in my job (roadway design primarily), is geometry.

 

I selected:
Real Analysis, Complex Analysis, Numerical Analysis, Other Applied Math
because I seem to remember dealing with the complex number i.

I don't quite remember how it is applied though (though I do know it's the square root of -1, so no need to explain that ).

 

Douglas Adams - essential reading for the serious (or not-so-serious) reader.

 

If x0 and x1 are both solutions of x^2 - a = 0, a > 0 (e.g., 2 and -2 are both solutions of x^2 - 4 = 0), then we call the larger of x0 an x1 (the positive value) "the square-root of a" and the other one is the negative of the square-root of a. Because both i and -i satisfy x^2 - (-1) = 0, we should call the larger one "the square-root of -1". So which is larger: i or -i?



PS You usually get introduced to i in an Algebra II or Trigonometry course; Complex Analysis deals with the topology of the complex numbers and the calculus of functions of complex variables.

 

and how old are you?

I once had a calculus class on the 9th floor. That was the highest math class I had. I had English lit on the 10th....
