Multiline equation write form in text cell?
Is there a way to write equation within text cell as few lines?
For example this:
$f(x) = y^x$
renders normally, but this:
$f(x) = y^x$
renders as plain text. I wan it to be rendered in the same way as first one.

# Break-even Point Equation Method
Break-even is the point of zero loss or profit. At break-even point, the revenues of the business are equal its total costs and its contribution margin equals its total fixed costs. Break-even point can be calculated by equation method, contribution method or graphical method. The eq... | |

An Ode To The Rice Cooker, The Smartest Kitchen Appliance I’ve Ever Owned
One of the first things I bought when I moved to college was a rice cooker. It was simple, the kind that costs 20 bucks at any old appliance or homeware store and has exactly two settings: on and off. Sure, it was hard ... | |
# A,B decidable: proof that A\B is decidable too
For an assignment I have to proof that for two given decidable languages A,B, A\B is decidable too.
My idea is as follows: If B is empty or doesnt have elements in common with A, then A\B is decidable because A\B=A.
If B is not empty and intersects with A, A\B is just... | |
Dealing with astronomy data means I often need to deal with information collecting. Most of the time the API from the websites is powerful enough, I don’t need to make any extra effort to clean the data. Once in a while, I am not happy with learning all the grammar of the API so I decide to act like a barbarian and do ... | |

There is currently an increased focus on the functional diversification of existing semiconductor process nodes to create new technologies1,2. This approach increases performance, supply chain resilience and security by reducing the number of chips from different process technologies that must be integrated and p... | |
The etale site of a closed subscheme and its etale Grothendieck subtopology
There is a very basic theorem for the Zariski topology.
Let X = Spec(R) and Y=Spec(R/I) for I some reduced ideal. Y obtains a topology two ways, one is the subspace topology as a subset of X and another as the spectrum of a ring. These topolo... | |

# Projective family of probability spaces
This is a crosspost of this question from MSE.
I'm confused about the definition of a projective family of probability spaces $(S_t,\mathscr S _t,\mu_t,f_{ts})_{s,t\in T}$. The conditions
• $f_{tt}=1_{S_t}$
• $f_{us}=f_{ts}\circ f_{ut}$ where $s\leq t\leq u$
are clear from ... | |
