The purpose of this paper is to collect and collate the famous works in the history of mathematics, so as to make it easier for friends who are interested in mathematics to read. The following time will be a short description for each book, so that you can understand its content.This article will continue to update"Element" translated "original", author Euclid."Mathematical Collection" translated "Mathematical compilation", the author Pappus a.d.

Square CoinsPoint MeProblem descriptionpeople in Silverland use square coins. Not only they has square shapes but also their values is square numbers. Coins with values of all square numbers up to 289 (=17^2), i.e, 1-credit Coins, 4-credit Coins, 9-credit Coins, ..., and 289-credit coins, is available in Silverland.There is four combinations of coins to pay ten credits:Ten 1-credit coins,One 4-credit coin and six 1-credit coins,4-credit coins and 1-credit coins, andOne 9-credit coin and one 1-cr

In the "To be built" line, it indicates the corresponding module that will eventually be compiled. If the Java environment is detected successfully, the "java" option must exist, as shown in row 3rd. If it is not found, it indicates that the Java Runtime Environment is not properly configured. You can use a co

For a shape SVG element or text SVG element, you can use Stroke-dasharray to control the stroke spacing style, and you can use Stroke-dashoffset to control the stroke offset, this can achieve the stroke animation effect, more specific information can see the big God "Pure CSS to achieve handsome SVG path stroke animation effect"Let's start by implementing a simple text stroke animation:svgwidth= "100%"Height= "+"> textT
