How to Understand and then Forever Memorize the Midpoint Formula
In algebra we have many formulas to learn. But one problem is that those formulas are often hard to memorize. They are written with variables, and the variables frequently have subscripts, and the truth is that a lot of us don’t really understand what th... | HuggingFaceTB/finemath | |

## Conversion formula
The conversion factor from kilometers per hour to knots is 0.53995680345662, which means that 1 kilometer per hour is equal to 0.53995680345662 knots:
1 km/h = 0.53995680345662 kt
To convert 167 kilometers per hour into knots we have to multiply 167 by the conversion factor in order to get the ... | HuggingFaceTB/finemath | |

When calculating decimals, a division is a bit more complicated. This is because it is not always divisible. You have to calculate until you can divide, or use the remainder to get the... | HuggingFaceTB/finemath | |
# derivation of unit vectors in curvilinear coordinates
Let $(u,v,w)$ be any non-Cartesian coordinate system such that
$\displaystyle x=x(u,v,w),\quad y=y(u,v,w),\quad z=z(u,v,w)$ (1)
We can combine the above three equations into a single vector equation that gives the position vector $\vec{r}$ of any point $P=(x,... | HuggingFaceTB/finemath | |

# Abstract Real Numbers: Fields
When I learned abstract algebra, we very nearly skipped over rings. Basically, we

category theory. I’m going to fo... | HuggingFaceTB/finemath | |
