The solution
You have entered
[src]
oo / | | 1 | -- dn | 2 | n | / 1
$$\int\limits_{1}^{\infty} \frac{1}{n^{2}}\, dn$$
Integral(1/(n^2), (n, 1, oo))
Detail solution
-
Add the constant of integration:
PiecewiseRule(subfunctions=[(ArctanRule(a=1, b=1, c=0, context=1/(n**2), symbol=n), False), (ArccothRule(a=1, b=1, c=0, context=1/(n**2), symbol=n), False), (ArctanhRule(a=1, b=1, c=0, context=1/(n**2), symbol=n), False)], context=1/(n**2), symbol=n)
The answer is:
The answer (Indefinite)

/ | | 1 | -- dn = nan | 2 | n | /
$$\int \frac{1}{n^{2}}\, dn = \text{NaN}$$
