Decide whether the statement made is True or False. The relation siny+ey=x6-x2+x+1 is an implicit solution to dydx=6x5-2x+1cosy+ey.

In Problems 15-24 , solve for Y(s), the Laplace transform of the solution ytto the given initial value problem.

y''+3y=t3;y0=0,y'0=0

In Problems 14鈥�24, you will need a computer and a programmed version of the vectorized classical fourth-order Runge鈥揔utta algorithm. (At the instructor鈥檚 discretion, other algorithms may be used.)鈥�

Using the vectorized Runge鈥揔utta algorithm for systems withh=0.175, approximate the solution to the initial value problemx'=2x-y;x(0)=0,y'=3x+6y;y(0)=-2 att=1.

Compare this approximation to the actual solution.

In Problems 9鈥�20, determine whether the equation is exact.

If it is, then solve it.

(2xy+3)dx+(x2-1)dy=0

Let 蠒(x)denote the solution to the initial value problem

dydx=x-y,y(0)=1

猞� Show that 蠒(x)=1-蠒'(x)=1-x+蠒(x)

猞� Argue that the graph of 蠒 is decreasing for x near zero and that as x increases from zero, 蠒(x)decreases until it crosses the line y = x, where its derivative is zero.

猞� Let x* be the abscissa of the point where the solution curve y=蠒(x) crosses the line y=x.Consider the sign of 蠒(x*) and argue that 蠒 has a relative minimum at x*.

猞� What can you say about the graph of y=蠒(x) for x > x*?

猞� Verify that y = x 鈥� 1 is a solution to dydx=x-y and explain why the graph of y=蠒(x) always stays above the line y=x-1.

猞� Sketch the direction field for dydx=x-y by using the method of isoclines or a computer software package.

猞� Sketch the solution y=蠒(x) using the direction field in part (f).
