The general solution of the DE ` (1+ x ^(2)) dy - xy dx = 0 ` isA. `y

1.	The general solution of the DE ` (1+ x ^(2)) dy - xy dx = 0 ` isA. `y = C (1 + x ^(2)) `B. `y ^(2) = c (1 + x ^(2)) `C. `y sqrt (1 + x ^(2)) = C `D. none of these
Answer» Correct Answer - B ` int (1)/(y) dy = (1)/(2) int (2x)/((1+x ^(2))) dx rArr log y = (1)/(2) log (1 + x ^(2)) + log C` `rArr log y = log (C sqrt ( 1+ x^(2))) rArr y = C sqrt (1 + x ^(2))` .
