An Interesting Equation of Order n: xy" - (x + n)y' + ny = 0: u(x) = e^x. (a) Prove that the given solution is indeed a solution
Igoryamba

Solution:

The given differential equation is

x y" -(x+n)y'+ny=0------------(1)

Let, y'=t

y"=t'

\frac{dy}{dx}=t\\\\y=t x

Substituting the value of , y', y'' and y in equation (1)

→x t' -(x+n)t+n t x=0

→ x t' = x t+ n t- nt x

→ x t'=t(x+n-nx)

\rightarrow \frac{t'}{t}=\frac{x+n-nx}{x}\\\\\rightarrow \frac{dt}{t}=(1-n+\frac{n}{x}) dx\\\\ \text{Integrating both sides}}\\\\ \int{\frac{dt}{t}}=\int {(1-n+\frac{n}{x}) dx}\\\\ \log t=x - nx+n \log x+\log K\\\\ \log t -\log x^n-\log K=x(1-n)\\\\\log \frac{t}{Kx^n}=x(1-n)\\\\t=Kx^n \times e^{x(1-n)}\\\\y'=Kx^n \times e^{x(1-n)}

which is a solution of Differential equation.

(b)

\frac{dy}{dx}=Kx^n\times e^{x(1-n)}\\\\ dy=Kx^n\times e^{x(1-n)} dx

Integrating both sides

y=\frac{Kx^n\times e^{x(1-n)}}{1-n}-\frac{Kn}{1-n}\int{x^{n-1}e^{x(1-n)} dx

required linear independent solution of Differential equation.

(1) Write the ratio of the volumes of the 500ml bottle and the 2-litre bottle of milk in its simplest form.
Vadim26 [7]

Answer:

1] 1 : 4

2] 250ml

Step-by-step explanation:

1] 500ml : 2 litre

First, the units must be the same.

<em> 2 litre = 2000ml</em>

500ml : 2000ml

     5 : 20

      <u>1 : 4</u>

<u></u>

2]  \frac{2}{4} × 500

= 250ml
