The time rate o f change o f the velocity v of a coasting motorboat is proportional’to the square of v.

In Example 5 of Section 3. Note that the Laplace transform method again gives the solution directly, without the necessity of first finding ecuacipnes complementary function and a particular solution of the original nonhomogeneous ecuacioness equation.

Also, resultthe constant-valued function y x c. The distance of each singular point from 4 is 5, so a series solution of the form x – 4 t has radius of convergence at least 5 see Fig.

A mass spring-dashpot system. If a ball is projected upward from the ground with initial velocity Vo and resistance proportional to v 2deduce from Eq. Suppose that one particular solution of this equation difrenciales known. With a computation similar to that shown in Example 4 but more complicated -see Problem 2 1the method of substitution can be used to derive the solutionHnwhere is defined in 44 for n shown in Eq.

Throughout these problems, primes denote derivatives with re spect to x.

Multivariable calculus edwards and penney 6th Use the method of Problem to derive both the solu tions in 38 and 45 of Bessel’s equation of order zero. The Parametric Bessel EquationThe parametric Bessel equation of order n isa 28 where is a positive parameter. It is rather awkward to compute the Taylor series of the tangent function using Eq.


Can you also use the “left half” of the cubic y x – c 3 in piecing together a solution curve of the differential equa tion? Henry 6th Edition By David E. Consider a body that moves horizontally through a medium whose resistance is proportional to the of the velocity v, so that dv d – v 2 Show that2,4.

How tall is the build ing? Theorem 3 provides the necessary nonvanishing of W in the case of linearly independent solutions. Thus these two different linear combinations with arbitrary constant coefficients provide two different descriptions of the set of all solutions of the same differential equation y” – 4 Y O. In terms of the arbitrary constants and Eq.

An important special value of the gamma function iswhere we have substituted u 2 for t in the first integral; the fact that Nonlinear systems like this ordinarily are solved numerically using an appropriate computer system. If it happens that 0, then there is no logarithmic term; if so, Eq. Proof of Theorem 3: The single language that the original Native Americans spoke has since split into many Indian “language families. With the formulation of this new mathematical model, we may attempt to traverse once again the diagram of Fig.

An accident at a nuclear power plant has left the surround ing area polluted with radioactive material that decays nat urally. To reach the moon, the projectile must only j ust pass the point between the moon and earth where its net acceleration vanishes. Calculus 6th Edition By David E.

Difefenciales n sforms of Higher DerivativesSuppose that the functions ff ‘, f”.

It is worth noting also that the formula in 5 holds if a is a complex number. Because of the wide availability of com puters, numerical techniques are commonly used to approximate the solutions of differential equations that cannot be solved readily or explicitly by the methods of diferenciaoes chapter.

Piecewise Continuous FunctionsAs we remarked at the beginning of this section, we need to descargae able to handle certain types of discontinuous functions.

To see if and when practical res onance occurs, we need only graph C as a function of w and look for a global maximum. Suppose, instead, that the initial condition in Example 1 had been In Problems through 10, find a power the radius conver In C for n 2 in 22, of derivec, recurrence relatio given diffethe 1resulting series,Determine the series inofEqs.

Suppose that in 1 the population of a certain country was 50 million and was growing at the rate ofpeople per year at that time. Exa m p l e 4Determine the radius of convergence guaranteed by Theorem of1of a series solution 6 in powers of x. That is, in order to solve an equation that can be written in the form in Eq.

We verify this assertion as follows: XY2Y2 b mula We will see that the constant M is now a threshold population, with the way the population behaves in the future depending critically on whether the initial population Po is less than or greater than M. Lest it appear eddwards these methods constitute a “grab bag” of special and unre lated techniques, it is important to note that they are all versions of a single idea.

We now rewrite Eq. So the general solution is 13 A motorboat weighs 32, lb and its motor provides a thrust of lb. If the car reaches B at 1 2: The identities edsards Eqs.
