There are times that we wanted to position an equation on the top right of the slide in beamer. The easiest way to do it is to use two packages: textpos and eso-pic. textpos package positions the textblock, while eso-pic sets up a grid system on the slides.

We include the two packages with options.


To position a textblock, use the options \begin{textblock}{WIDTH}(XCOORDINATE,YCOORDINATE). Here is an example.

    \mathbf {H} = \frac{1}{2}\left( - \omega_{\mathrm{m}} + {\color{red}\delta \lambda(x)} \cos 2\theta_{\mathrm{m}} \right) \sigma_3 - \frac{  {\color{red}\delta \lambda(x)}  }{2} \sin \theta_{\mathrm{m}} \sigma_1
