Question

The solution of the DE `x cos y dy = (x e ^(x) log x + e ^(x)) dx ` is
A. `sin y = e ^(x) + log x + C `
B. ` sin y - e ^(x) +log x = C `
C. `sin y = e ^(x) (log x ) + C `
D. none of these

Answer 1

Correct Answer - C
`int cos y dy = int e ^(x) (log x + (1)/(x) ) dx rArr sin y = e ^(x) log x + C`.
