Choose the correct alternative:
If y = ex + c – c3 then its differential equation is
विकल्प
`y = x ("d"y)/("d"x) + ("d"y)/("d"x) - (("d"y)/("d'x))^3`
`y + (("d"y)/("d"x))^3 = x ("d"y)/("d"x) - ("d"y)/("d"x)`
`("d"y)/("d"x) + y = (("d"y)/("d"x))^3 - x ("d"y)/("d"x)`
`("d"^3y)/("d"x^3) = 0`
उत्तर
`y = x ("d"y)/("d"x) + ("d"y)/("d"x) - (("d"y)/("d'x))^3`
