Integrating factors allow us to solve equations of the form $y' + P(x)y = Q(x)$
# Intuition
The derivative of $e^{R(x)}$ is $R'(x) e^{R(x)}$ . This can be used to cancel out terms when we have anything of the form $y' + R'(x)y$, and we can do by setting $P(x) = R'(x)$ . By playing around ... | {} |
Maps of maximal ideals
Prove that $\mu:k^n\rightarrow \text{maximal ideal}\in k[x_1,\ldots,x_n]$ by $$(a_1,\ldots,a_n)\rightarrow (x_1-a_1,\ldots,x_n-a_n)$$ is an injection, and given an example of a field $k$ for which $\mu$ is not a surjection.
The first part is clear, but the second part needs a field $k$ such tha... | {} |
# Can a function be square integrable without being integrable?
Reading Tolstov's 'Fourier Series', which states that $f(x)$ is square integrable if both $f$ and its square both have finite integrals over some interval. I haven't seen this restriction on $f$ before, which makes me wonder - can squaring a function ever... | {} |

# Is it possible to measure the density of a supermassive black hole?
Jun 4, 2018
Yes, the density of a black hole can be calculated from its mass.
#### Explanation:
The mass of a supermassive black hole can be estimated from the period and semi-major axis distance of a star orbiting it.
In our galaxy there is a s... | {} |

# How do you find the definite integrals for the lengths of the curves, but do not evaluate the integrals for y=x^3, 0<=x<=1?
Mar 14, 2018
$A = {\int}_{0}^{1} \sqrt{1 + 9 {x}^{4}} \mathrm{dx}$
#### Explanation:
Recall that the arc length of a curve is given by
$A = {\int}_{a}^{b} \sqrt{1 + {\left(\frac{\mathrm{dy}... | {} |

Let $x(w, q)$ denote the solution to the cost minimization problem : \begin{eqnarray*} \min_{x} & \ w\cdot x \\ \text{s.t.} & \ \ f(x) \geq q \end{eqnarray*} where $f$ is the production function. Since $x(w, q)$ minimizes cost at $(w, q)$, following holds for all $w$ and for ... | {} |

The strain energy release rate (or simply energy release rate) is the energy dissipated during fracture per unit of newly created fracture surface area. This quantity is central to fracture mechanics because the energy that must be supplied to a crack tip for it to grow must be balanced by... | {} |
