Condition numbers of Vandermonde quasimatrices
A Vandermonde quasimatrix can be made like this in Chebfun:
x = chebfun('x');
A = x.^(0:10);
This particular example has 11 columns corresponding to the functions $1, x, \dots, x^n$ with $n=10$, and it is quite ill-conditioned:
cond(A)

Probability can be a bit counter-intuitive at times. Take for example, the birthday problem / paradox: how many people do you need in a room to have a 50/50 chance that two share the same birthday?
Turns out, it’s not as many as you might think: you only need 23.
Why? Math!

Is it possible to make Acos return values greater than pi?
