Math blogs, SAGE, and latex

Posted on by

I only created this wordpress site thinking that I could not type LaTeX on my blogspot page (wdjoyner.blogspot.com). Since I figured out how, following http://wolverinex02.googlepages.com/emoticonsforblogger2, maybe this blog will stay dormant for now.

A latex test:

\frac{\pi}{4}=\int_0^1 \frac{dx}{1+x^2} is smallest

\frac{\pi}{4}=\int_0^1 \frac{dx}{1+x^2}

\frac{\pi}{4}=\int_0^1 \frac{dx}{1+x^2}

\frac{\pi}{4}=\int_0^1 \frac{dx}{1+x^2}

\frac{\pi}{4}=\int_0^1 \frac{dx}{1+x^2}

\frac{\pi}{4}=\int_0^1 \frac{dx}{1+x^2} is biggest

Here is a SAGE plot of the integrand:

Here is a SAGE session:


sage: x = var("x")
sage: integral(1/(1+x^2),x,0,1)
pi/4
sage: plot(1/(1+x^2),x,0,1)

Actually, I like this much better than blogspot, so I might switch after all!
