There have been several posts lately, of a mathy nature, that could really benefit from some nice math formatting options.  

 

Could someone add Latex functionality to the list of board enchancements?

·   Example: The kinematic states evolve dynamically according to a linear state space model (3):

 

(3)

 

where F(T) is the state transition matrix of the target state model, and wi(T) is the driving maneuver input.

 

 

 Paste from Word did not work for the equation but the last line came out correctly.
