How to write LaTeX in IPython Notebook?

Just put your LaTeX math inside $$. $$c = \sqrt{a^2 + b^2}$$ Or you can display LaTeX / Math output from Python, as seen towards the end of the notebook tour: from IPython.display import display, Math, Latex display(Math(r’F(k) = \int_{-\infty}^{\infty} f(x) e^{2\pi i k} dx’))

Getting LaTeX into R Plots

The CRAN package latex2exp contains a TeX function that translate LaTeX formulas to R’s plotmath expressions. You can use it anywhere you could enter mathematical annotations, such as axis labels, legend labels, and general text. For example: x <- seq(0, 4, length.out=100) alpha <- 1:5 plot(x, xlim=c(0, 4), ylim=c(0, 10), xlab=’x’, ylab=TeX(r'($\alpha x^\alpha$, where $\alpha … Read more
