The distance to the horizon depends on how high you are observing it.
If you are 5'6'’, standing on the shoreline, the horizon appears 2.75 miles away from you.
In this article, you learn how to calculate the distance to the horizon with a simple formula.
To find the inverse function, follow these four steps:
f(x) with y).x and y.y.y with f^(-1)(x)).Find the inverse function of
To calculate the volume of a cube with a side length a, use the following formula:
There are 4 quarts in 1 gallon.
This is easy to remember. Consider the word “quart”. It refers to a quarter.
When speaking about volumes, a quart is a quarter of a gallon. In other words, it is one-fourth of a gallon—so there are four of them in a gallon.
The resolution for 4k is
3840 x 2160This means a 4k screen has a whopping 8.3 million pixels in total. This is 36 times more than a good old 480p SD screen!
The 4k refers to 4000. But the resolution of 4k is “only” 3840 x 2160.
The reason…
Python switch-case statements are here! And they are actually called match-case statements.
This means you can soon replace this type of if-else mess:
