Assignment 23 indefinite integral of several kinds of special functions

(1)\[\begin{aligned}\int \frac{x}{x^2+2x-3}dx= \int \frac{x-1+1}{(x+3) (x-1)}DX= \int \frac{1}{x+3} + \frac14 \frac{4}{(x+3) (x-1)} DX\\=\int \frac{1}{x+3} + \frac14 \frac{(x+3)-(X-1)} {(x+3) (x-1)} DX= \int \frac{3/4}{x+3}-+ \frac{1/4}{x-1} DX=

Multi-precision PI computing Assembly implementation

The PI program on vier gourdon is a good start for computing, piclassic. I downloaded the C program and compiled it with/O2. I found that it is still a little faster than I did without changing my mind. Of course it cannot be compared with the above
