1. Y=Ae^x+Bxe^x Solve differential equation?


Step-by-step explanation:

There are many differential equations where y=Ax2+Bxex is a solution, although some of them might have other solutions as well.

On our first attempt, we can try to find a linear homogeneous equation with constant coefficients. Usually, when we are given such a problem, we set up a characteristic polynomial equation, then solve it, and finally we use the roots to this equation to find solutions to the differential equation.

But here, we’ll work backwards by finding roots of characteristic equation first, and then finding the characteristic equation, and finally the differential equation.

If characteristic equation has real root r with multiplicity n, then general solution is:

y=erx(c1+c2x+⋯cnxn−1)

So we need to find r and smallest value of n that will fit each of the two linearly independent solutions.

y=Ax2=Ae0xx3–1⟹r=0,n=3⟹r3=0

y=Bxex=Be1xx2–1⟹r=1,n=2⟹(r−1)2=0

Therefore characteristic equation has roots r3 and (r−1)2

r3(r−1)2=0

r3(r2−2r+1)=0

r5−2r4+r3=0

The differential equation that matches characteristic equation is:

y(5)−2y(4)+y(3)=0

Unfortunately, this differential equation has general solution:

y=c1x2+c2x+c3+c4xex+c5ex

If you need to eliminate the unnecessary terms, you can use initial conditions, such as:

y(0)=0

y(3)(0)=3y′(0)

y(4)=43y(3)

Plugging into WolframAlpha (with initial conditions), we get:

Wolfram|Alpha

y=13x(c1ex+c2x)=c23x2+c13xex=Ax2+Bxex

However, if we want to find a differential equation that only has the two linearly independent solutions shown, and without using initial conditions, we’ll need to find a second order differential equation. And each time we differentiate, we’ll need to eliminate one of the constants.

y=Ax2+Bxex⟹Ax2=y−Bxex

Differentiate:

y′=2Ax+Bxex+Bex

xy′=2Ax2+Bx2ex+Bxex

Eliminate constant A:

xy′=2(y−Bxex)+Bx2ex+Bxex

xy′=2y+Bx2ex−Bxex⟹Bex=xy′−2yx(x−1)

Differentiate again:

xy′′+y′=2y′+Bx2ex+2Bxex−Bxex−Bex

xy′′−y′=Bex(x2+x−1)

Eliminate constant B:

xy′′−y′=xy′−2yx(x−1)(x2+x−1)

x2(x−1)y′′−x(x−1)y′=x(x2+x−1)y′−2(x2+x−1)y

x2(x−1)y′′−x(x2+2x−2)y′+2(x2+x−1)y=0  

   

y=c21−x−−−−−√x2x−1−−−−−√+c1ex1−x−−−−−√xx−1−−−−−√=c2ix2+c1ixex=Ax2+Bxex


2. eliminate the arbitrary constant on y=ae^x +bxe^x

6. If AE = 2x + 10 and CE = 6x – 30, find AC.


Answer: AC=60

Step-by-step explanation: If AE is equal to CE (The midpoint is E)

So the equation is

2x+10=6x-30

2x-6x=-10-30

-4x=-40

x=10

then

2x+10

2(10)+10

20+10

=30

then

AC is the diagonal so 30x2 is

60

AE=30

CE=30

22. if AE=(5x-5) cm, and CE= (2x+7)cm, find x and AC


Step-by-step explanation:

AE = 5x - 5

CE = 2x + 7

Subtract AE and CE

0 = 7x -12

Add 12 to both sides

12 = 7x

Divide both sides by 7

x = 12/7

AC = AE - CE

= (5x - 5) - (2x + 7)

= 3x - 12

= (3 x (12/7)) - 12

= 24/7 - 12

= 12/7 cm
