I have this macro that I use in every animation:

#macro Transition(Start,End,Swerve,Phase)
   #local tP=min(1,max(0,Phase))*pi;
   #local aL=(1-cos(tP))/2;
   #local aS=(1-cos(tP*2))/2;
   ( (Start)+(End-Start)*aL + (Swerve)*aS )
#end

This is quite good for most applications.  Start and End are 
self-explanatory.  Swerve allows movement to the side at the mid-point 
of the motion.  Phase controls the timine of the motion, so for 
animations you should put a clock-based value in here.

Hope this helps,
John
