Differentiation problem in Maxima



Dear Professor Fateman,

Many sincere thanks for your reply with respect to 
newdiff too. This is a definitive reply and a valuable
piece of information I have been unaware of and it 
seems not included in the Symbolics Macsyma User's
Guide (January 1988 edition) I have (officially) available 
here and try to study during this period.

Kindest regards from Patras,

Nikolaos I. Ioakimidis
