I have the simple program:
a = var('a')
b = 1/a
for i in (1..5):
c = b+1
b = 1/c
print b,",", c
The result is:
1/(1/a + 1) , 1/a + 1
1/(1/(1/a + 1) + 1) , 1/(1/a + 1) + 1
1/(1/(1/(1/a + 1) + 1) + 1) , 1/(1/(1/a + 1) + 1) + 1
1/(1/(1/(1/(1/a + 1) + 1) + 1) + 1) , 1/(1/(1/(1/a + 1) + 1) + 1) + 1
1/(1/(1/(1/(1/(1/a + 1) + 1) + 1) + 1) + 1) , 1/(1/(1/(1/(1/a + 1) + 1) + 1) + 1) + 1
Is there a way to get simpler expressions?
