The first blog post is usually some general introduction about the writer. I don’t like those posts so I start by testing my MathML installation.

To test it, let me try to write the “sombrero” function:

z={sin(sqrt(x^2 + y^2))} / sqrt (x^2 + y^2)

which is automagically constructed by Ron Fredericks‘ WP Math Publisher plugin using this line of code:


[ pmath size=12]
z=sin (sqrt (x^2 + y^2)) / (sqrt (x^2 + y^2))[ /pmath]
