Here are some useful shortcuts. 

  • ^ -- raise to a power.

  • sqrt -- create a root symbol

  • integrals
    • int for an indefinite integral
    • cint for a contour integral
    • dint for a definite integral


  • union/intersection

    • cup for a union
    • cap for an intersection

  • pi -- create the greek letter


  • arcsin, arccos, arctan -- inverse trigonometric functions


  • po -- create (,) notation for a point

  • (,) -- create notation for an interval

  • vectors

    • vec + symbol for an arrow notation of a vector named symbol
    • vec + < or <> for an angle brackets notation
    • vi or vx, vj or vy, vk or vz for a unit vector (<1,0,0>, <0,1,0>, <0,0,1> respectively)
