Answer:

The solution containing one arbitrary constant is 2y2+4=x2-12+C, and with boundary condition, the value of the constant is C = 0. The particular solution is 2y4+14=x2-12. The plot of a slope field and some solution curves are as follows:

Step by step solution

01

Given information

The given differential equation is y'=2xy2+xx2y-ywith boundaries y = 0 whenx=2.

02

Definition of differential equation

A differential equation is a mathematical equation that connects one or more unknown functions with their derivatives. The study of differential equations primarily entails looking at their solutions (the set of functions that satisfy each equation) and characteristics.

03

Separate the variables

Separate the variables in y'=2xy2+xx2-yand keep y on one side and x on the other.

dydx=2xy2+xx2y-ydydx=x2y2+1yx2-1y2y2+1dy=xx2-1dx

04

Integrate the differential equation

Integrate the above differential equation using the variable separable form.

Substitute,

2y2+1-tydy-14dtx2-1-usdx-12du

Solve the separated form of the differential equation with an arbitrary constant C.

y2y2+1dy=x22-1dx14dtt=12duu14Int=12Inu+ct4=u2C

Re-substitute t=2y2+1and u=x2-1in the above equation.

2y2+14=x2-12+C …… (1)

05

Find the value of the arbitrary constant and particular solution

Put the boundary conditions, y = 0 when x=2, in (1) and find the value of C.

202+14=22-12+C1=2-12+C1=1+CC=0

Substitute the value of C in (1) and find the particular solution.

2y2+14=x2-12

06

Plot the slope field

Plot the slope field of 1+y2dx+xydy=0and some solution curves.

Therefore, for the differential equation y'=2xy2+xx2y-y, the solution containing one arbitrary constant is 2y2+14=x2-12+C, and with boundary condition, y = 0 when x=2. The value of the constant is C = 0 and the particular solution is 2y2+14=x2-12.The plot of a slope field and some solution curves are as follows.

The speed of a particle on the x axis, x0, is always numerically equal to the square root of its displacement x. If x=0when t=0, find x as a function of t. Show that the given conditions are satisfied if the particle remains at the origin for any arbitrary length of time t0and then moves away; find x for t>t0for this case.

Sketch on the same axes graphs ofsint,sin(t-π/2), andsin(t+π/2), and observe which way the graph shifts. Hint: You can, of course, have your calculator or computer plot these for you, but it's simpler and much more useful to do it in your head. Hint: What values of tmake the sines equal to zero? For an even simpler example, sketch on the same axesy=t,y=t-π/2,y=t+π/2.

Using Problems 29 and 31b, show that equation (6.24) is correct.

Several Terms on the Right-Hand Side: Principle of Superposition So far we have brushed over a question which may have occurred to you: What do we do if there are several terms on the right-hand side of the equation involving different exponentials?

In Problem 33 to 38 , solve the given differential equations by using the principle of superposition [see the solution of equation (6.29) . For example, in Problem 33 , solve three differential equations with right-hand sides equal to the three different brackets. Note that terms with the same exponential factor are kept together; thus a polynomial of any degree is kept together in one bracket.
