प्रश्न
For the following equations, determine its order, degree (if exists)
`sqrt(("d"y)/("d"x)) - 4 ("d"y)/("d"x) - 7x` = 0
उत्तर
`sqrt(("d"y)/("d"x)) = 4 ("d"y)/("d"x) + 7x`
On squaring both sides,
`("d"y)/("d"x) = 16(("d"y)/("d"x))^2 + 49x^2 + 56x ("d"y)/("d"x)`
clearly, it is a differential equation of order = 1 and degree = 2.
