g Suppose that the populationy(t)of a certain kind of fish is given by the logistic modely′= 3y−2y2(a) Solve the Bernoulli equat
Ksju [112]

Answer:

y = \frac{3}{2 + 3Ce^{-3t} }

Step-by-step explanation:

As given , y' = 3y - 2y²

⇒y' - 3y = -2y²

Divide by y² in the above equation

⇒\frac{y'}{y^{2} } - \frac{3y}{y^{2} } = -\frac{2y^{2} }{y^{2} }

⇒\frac{y'}{y^{2} } - \frac{3}{y } = -2       ........(1)

Now , let \frac{1}{y} = u

⇒-\frac{1}{y^{2} } \frac{dy}{dt} = \frac{du}{dt}

⇒-\frac{1}{y^{2} }y' = \frac{du}{dt}

∴ equation (1) becomes

-\frac{du}{dt} - 3u = -2

⇒\frac{du}{dt} + 3u = 2

It is a linear differential equation

Now,

Integrating factor = I.F = e^{\int\limits {3} \, dt } = e^{3t}

∴ The solution becomes

u.(I.F) = \int\limits {2.(I.F)} \, dt + C

⇒u.(e^{3t}) = \int\limits {2.(e^{3t} )} \, dt + C

⇒u.(e^{3t}) = \frac{2e^{3t} }{3} + C

⇒u = \frac{2}{3} + Ce^{-3t}

As \frac{1}{y} = u

⇒\frac{1}{y}  = \frac{2}{3} + Ce^{-3t}

⇒ y = \frac{1}{\frac{2}{3} + Ce^{-3t}  } = \frac{3}{2 + 3Ce^{-3t} }

⇒ y = \frac{3}{2 + 3Ce^{-3t} }
