Hi,

I am working with equations on Maple which depends on a parameter (epsilon), which can assume only the values +1 and -1 (I intent to replace this value only in the end of calculation). When, however, Maple computes the expressions, the result contains severals powers of epsilon, for instance epsilon^7 or epsilon^4. Since actually we have that epsilon^7=epsilon and epsilon^4=1, respectively, it would be very usefull to me if Maple recognizes this fact and made the simplifications, as above.

 

Someone knows how I would define epsilon in this way and make the Maple to do that substitutions?

 

I appreciate very much the attention, cordially,

 

Ricardo Vieira.
