Description:
The solution to some common problems is proposed,
as well as a summary of some small functions. In particular,
it provides a useful function for some problems in chemistry.
For example, monoa(), monob() and mono() function can be used
to calculate The pH of weak acid/base.
The ggpng() function can save the PNG format with transparent background.
The period_table() function will show the periodic table. Also the
show_ruler() function will show the ruler.
The show_color() function is funny and easier to show colors.
I also provide the symb() function to generate multiple symbols at once.
The csv2vcf() function provides an easy method to generate a file.
The sym2poly() and sym2coef() function can extract coefficients from
polynomials.
