प्रश्न

Solve yx2dx + e–x dy = 0

बेरीज

उत्तर

yx2dx + e–x dy = 0

ex dy = – yx2dx

`1/y "d"y = - x^2 "e"^x  "d"x`

Integrating on both sides

`int 1/y  "d"y = - int x^2 "e"^x  "d"x`

log y = `[(x^2) "e"^x - (2x)"e"^x + 2"e"^x] + "c"`

`log y = - "e"^x [x^2 - 2x + 2] + "c"`

`"e"^x (x^2 - 2x + 2) + log y` = c

log y = `- "e"^x [x^2 - 2x + 2] + "c"`

`"e"^x (x^2 - 2x + 2) + log y` = c
