This is an attempt to get a list going of books in mathematics (algebra, topology, geometry etc.) that in the spirit of Terence Tao's An Introduction...

By considering the 2-norm(least squares) approximation of $f(x)=e^x$ for $-1\le x\le 1$ by a polynomial of degree $N$ which is expanded into a series of L...

I want to compute the CDF of a Pareto distribution In particular, I have a Pareto distribution with p.d.f. $$f(x) = \lambda x^{-(\lambda + 1)},$$ and I wa...

Am I cubing these units? If so how? My thinking? decimeter =10^-1 = 0.1, centimeter 10^-2= 0.01 If 1 liter = 1 cubic decimeter, how can it also equal 1000...

I have the straight lines: $$d_1: \frac{x-1}2=\frac{y-3}1=\frac{z+2}1\\[4ex] d_2: \dfrac{x-1}1=\frac{y+2}{-4}=\frac{z-9}2$$ And I have to find the common ...

You have two 6-sided dice. You roll them and get a total of 10. You roll again and get a total of 9. If you get paid 1$ for each 5 that is rolled what is ...

Would you please give me a concrete example for the following definitions? Specifically I don't understand why a choice function is defined as $c: B ...

I have been studying differential equation, in particular special functions. Euler's Gamma function, and Gauss's Pi function are essentially the...

I know what the frobenius map is the naive sense, just the $p$th power map on an $\mathbb{F}_p$ algebra, and that this can be upgraded somewhat to the gen...

how can I calculate $ d = 17^{-1} (\text{mod} ~ 60) $ ? I was reading this article and then I wrote down this steps: 60 = 3 * 17 + 9 17 = 1 * 9 + 8 9 = 1 ...
