The solution of the DE ` (dy)/(dx) + y log y cot x = 0 ` isA. `cos x log y =C `B. `sin x log y= C `C. ` log y = C sin x `D. none of these |
|
Answer» Correct Answer - B ` (1)/( y log y ) dy + cot xdx = 0 rArr (dy)/(y log y) + int cot x dx = log C ` `rArr log ( log y ) + log sinx = log C rArr log (sin x + log y ) =log C ` `rArr (sin x ) log y = C `. |
