## Question:Strange !! Maple makes mistakes ! What am I doing wrong ?

Maple
Already posted this in my previous thread, but as it is different from the initial topic thought I would post it seperately So I'm playing with integer series and polynoms and it looks like Maple makes mistakes !! What am I doing wrong in below sheet ? View 3284_test2.mw on MapleNet or Download 3284_test2.mw
View file details The result provided by Maple is obviously wrong as all these functions should be positive. and using below Python code to get the result :
```def D1(p):
return 1

def D2(p):
if p<2:
print "D2 error" , p
else:
return p-1

def D3(p):
r=0
if p<3:
print "D3 error" , p
else :
i=1
while i <= p-2:
r+=D2(p-i)
i+=1
return r

def D4(p):
r=0
if p<4:
print "D4 error" , p
else :
i=1
while i <= p-3:
r+=D3(p-i)
i+=1
return r

def D5(p):
r=0
if p```
I get D5(14)= 715 but not the nice polynoms to express the functions ... Any info on what's wrong with the sheet ?
