What I'm doing: Drooling over how awesome math and physics are (and how deeply they connect), but more precisely, an applied mathematics degree and an applied physics degree.

### Re: Pi Day

I agree with Yakk, cold pies ftw. Today I'll just take the time to appreciate circles everywhere. No squares allowed.

### Re: Finding a function that meets these conditions

Yeah, the two functions I suggested don't have matching concavity, I produced that example quickly, but jestingrabbit is right. I guess I'm still a little confused at what exactly the OP is looking for.

### Re: Finding a function that meets these conditions

I'm not sure if I read your post incorrectly, but are you trying to have this defined piecewise? If that is the case, you can just use y=ln(x)+2 (or something of this nature) defined from 0 to 1, and y=x+1 (or something of this nature) from 1 to infinity. When differentiated at x=1, both of these wi...

### Re: Area of Circle to Volume of Sphere

You are on the right track. But think about what exactly you are doing when you integrate to find a volume: you are taking cross section slices of the shape and summing up the areas of these slices as the number of slices you take goes to infinity (the thickness of the cuts gets infinitesimally smal...

### Re: What to learn?!?

Have you considered taking any diff eq classes or multi-variable calc classes? Both of these are great and have linear algebra applications which is something you have some preexisting knowledge of. Also, an analysis class would be good and the things you'll learn carry over into almost any field of...
