# How do you simplify |8-sqrt289|?
First, let's simplify the expression by subtracting $\sqrt{289}$ from 8:
$\left\mid 8 - \sqrt{289} \right\mid = \left\mid - 9 \right\mid$
Now, the absolute value of a number is the magnitude of the number, regardless of its sign (positive or negative). In your case, the absolute valu... | {} |
# Solving a non-linear system of equations symbolically [closed]
How would I solve this systems of non-linear equations symbolically:
$$\mu N -\frac{\beta S I}{N} - \nu S = 0 \qquad (1)$$
$$\frac{\beta S I}{N} -\gamma I - \nu I = 0 \qquad (2)$$
$$\gamma I - \nu R = 0 \qquad (3)$$
where $$S+I+R=N$$ and $$\mu, \beta... | {} |

# Sampling from the Birkhoff polytope
The set of $n\times n$ real, nonnegative matrices whose rows and columns sum to one forms the well-known Birkhoff polytope
Recently someone asked me if I knew
How to sample (in polynomial time) uniformly at random, from the Birkhoff polytope?
Clearly, modulo a few hacks, I did ... | {} |
# Measurement of the intrinsic electron neutrino component in the T2K neutrino beam with the ND280 detector
Abstract : The T2K experiment has reported the first observation of the appearance of electron neutrinos in a muon neutrino beam. The main and irreducible background to the appearance signal comes from the prese... | {} |
# Volume of Sphere
## Exercise 13.8
Question 1: Find the volume of a sphere whose radius is
(i) 7 cm
Answer: Volume of sphere =4/3πr^3
=4/3xx(22)/7xx7^3=1437.33 cubic cm
(ii) 0.63 m
Answer: Volume of sphere =4/3πr^3
=4/3xx(22)/7xx0.63^3=1.047 cubic m

# Why can we assume that asset return rates are normally (or lognormally) distributed?
In many theories of financial mathematics it is assumed that asset return rates are normally distributed (e.g. VaR models) or lognormally distributed (e.g. Black-Scholes model). In practice, asset return rates are neither normally d... | {} |
The problem is very simple: write a program that accepts a single unsigned integer from the command line, and prints out that many random numbers on the standard output, in ascending order.
For example:
input:
5
output (you can use any type of whitespace):

# I Rearranging equation with more than variable instance
1. Aug 18, 2016
### Jehannum
This question is no doubt absurdly simple to many here, but the answer will help me immensely.
Say that:
c = a ^ 4
Then it's simple to rearrange for a:
a = c ^ 0.25
But what if there is more than one term, for example:
c = a... | {} |
