Re: Unhappy with my graduate school

I have done plenty of reading courses, research in my undergrad. This is not a question of being spoofed. The programs requirements are light, and the time requires to actually form a solid foundation on what they have glazed over would take weeks I do not have. I can't turn my back on program requi...

Unhappy with my graduate school

So I am going to graduate school for an MSc in quantitative finance in Vienna. I did my undergrad at UCSD in math. I am applying for phds in math, entirely on my UCSD background. The school I am currently at I am just beginning my second and last year at, and what was before what had become pretty d...

Re: Group theory: do some sets have implied operations?

Re: Turning a TI-84 into a TI-89

Using the tools available to you does not make you weak until you rely on the tools to do all the work. Does the fact that we have nail guns and air compressors somehow make a carpenter today less hardcore than a carpenter in 1815? No. Instead, we build better houses. Today's carpenter would only b...

This is really just a rewording of some posts but sometimes phraseology can make all the difference,

if the factorial function describes the number of arrangements of n elements, there is only one way you can arrange zero elements.

There is also a solution that involves rotating many squares but that method was only really found by the people that didnt see the first two and spent hours on it.
