I've been trying to write an article for a long time and talk to you:\frac{1}{1^2}+\frac{1}{2^2} +\frac{1}{3^2} +\frac{1}{4^2} +\frac{1}{5^2} +\cdots\ =\ \frac{π^2}{6}But there has been no chance, this summer vacation just have free, so the hand

The Math object is different from the above object. It can be said to be a common mathematics class, which has many mathematical methods used for various mathematical operations, but Math objects do not need to be constructed, you can directly use

Recently, we have been working on this coordinate transformation task, which involves many profound things such as surveyors. Here I will not explain these difficult theories. Here, I will post the code to share with you. In fact, if you want to
