Question

Integral of (y^2+4) * y^-1 dy. I think this by parts.

Answer 1

multiply (y^2+4) and y^(-1)
then integrate

Answer 2

\[\int\limits_{}^{}(y+4y^{-1}) dy=?\]

Answer 3

(Y^2+4)/y

Answer 4

\[\int\limits_{}^{}y~dy+\int\limits_{}^{}\frac{4}{y}~dy\]
Integration by parts is not needed, it's just linearity
