Question

x^3y''' - x^2y'' - 3xy' =3x

Answer #1

x^2y''-3xy'+3y=x^-2

x^3y’’’+3x^2y”+2xy’=0

Solve the following nonhomogenous Cauchy-Euler equations for x
> 0.
a. x^(2)y′′+3xy′−3y=3x^(2).

Show that the function f(z) =x^3-3xy^2+i((3x^2y-y^3) is
differentiable

Solve for the general solution
x^4y''''+4x^3y'''+3x^2y''-xy'+y=0

use gauss Jordan to solve
5x+11y+5z=42
x+2y+2z=9
3x+3y+2z=35

Verify that the given function is the solution of the initial
value problem.
1. A) x^3y'''-3x^2y''+6xy'-6y= -(24/x) y(-1)=0 y'(-1)=0
y''(-1)=0
y=-6x-8x^2-3x^3+(1/x)
C) xy'''-y''-xy'+y^2= x^2 y(1)=2 y'(1)=5 y''(1)=-1
y=-x^2-2+2e^(x-1-e^-(x-1))+4x

5. The planes: 2x − 3y + z = 1 and 3x − 2y − z = 0 …
(Explain/Show your Work)
a. Are parallel
b. Are Coincident
c. Meet in a Line
d. Meet at a Point

Consider the following system of equations.
3x
−
2y
=
b1
4x
+
3y
=
b2
(a) Write the system of equations as a matrix equation.
x
y
=
b1
b2
(b) Solve the system of equations by using the inverse of the
coefficient matrix.(i) where
b1 = −6, b2 = 11
(x, y) =
(ii) where
b1 = 4, b2 = −2
(x, y) =

Use
Gaussian Elimination to solve and show all steps:
1. (x+4y=6)
(1/2x+1/3y=1/2)
2. (x-2y+3z=7)
(-3x+y+2z=-5)
(2x+2y+z=3)
