Testing Math

All I want to do here is to see if I can enter an equation and have it look OK:

∫ dx cos(x) = sin(x) + C

∑_k=1,...n 1/k ≈ log(n) + γ + 1/(2n)

Well, it's not great but it could be worse.

For hints on how to do this (as well as more info on HTML in general) see here and here.


Here's some stuff I copied from another page, to keep around for reference. This obviously needs work - I need to learn some more HTML!!

√(a² + b²)



√(a² + b²)

square root of ( a^2 + b^2 )
