(1 pt) Just as there are simultaneous algebraic equations (where a pair of numbers have to satisfy a pair of equations) there are systems of differential equations, (where a pair of functions have to satisfy a pair of differential equations). Indicate which pairs of functions satisfy this system. It will take some time to make all of the calculations. 5 3 y1 = y1 y2 2 2 3 5 y2 = y1 + y2 2 2 y2 = cos(x) sin(x) A. y1 = sin(x) + cos(x) B. y1 = ex y2 = ex C. y1 = ex y2 = ex 2x D. y1 = 2e y2 = 3e2x 4x E. y1 = e y2 = e4x F. y1 = sin(x) y2 = cos(x) G. y1 = cos(x) y2 = sin(x) -9200 As you can see, nding all of the solutions, particularly of a system of equations, can be complicated and time consuming. It helps greatly if we study the structure of the family of solutions to the equations. Then if we nd a few solutions we will be able to predict the rest of the solutions using the structure of the family of solutions. Correct Answers: CE 9. (1 pt) It is easy to check that for any value of c, the function y = ce2x + ex is solution of equation y + 2y = ex . Find the value of c for which the solution satises the initial condition y(4) = 10. c= Correct Answers: 29754.9817203841 6. (1 pt) It can be helpful to classify a differential equation, so that we can predict the techniques that might help us to nd a function which solves the equation. Two classications are the order of the equation (what is the highest number of derivatives involved) and whether or not the equation is linear . Linearity is important because the structure of the the family of solutions to a linear equation is fairly simple. Linear equations can usually be solved completely and explicitly. Determine whether or not each equation is linear: + sin(t + y) = sin t dt 2 ? 2. y y + t 2 = 0 dy d2y ? 3. t 2 2 + t + 2y = sin t dt dt ? 4. y y + y2 = 0 ? 1. Correct Answers: 2Nonlinear 2Linear 2Linear 2Nonlinear 10. (1 pt) The family of functions y = ce2x + ex is solution of the equation y + 2y = ex . Find the constant c which denes the solution which also satises the initial condition y(5) = 2. c= Correct Answers: -0.0066471471395605 d2y 11. (1 pt) Find the two values of k for which y(x) = ekx is a solution of the differential equation y 12y + 27y = 0. smaller value = larger value = Correct Answers: 3 9 7. (1 pt) It is easy to check that for any value of c, the function c y = x2 + 2 x is solution of equation xy + 2y = 4x2 , (x > 0). Find the value of c for which the solution satises the initial condition y(7) = 1. c= Correct Answers: -2352 12. (1 pt) Find all values of k for which the function y = sin(kt ) satises the differential equation y + 20y = 0. Separate your answers by commas. Correct Answers: 8. (1 pt) The functions y = x2 + are all solutions of equation: xy + 2y = 4x2 , (x > 0). Find the constant c which produces a solution which also satises the initial condition y(10) = 8. c= Correct Answers: 2 c x2 4.47213595499958, -4.47213595499958, 0 13. (1 pt) Find the value of k for which the constant function dx x(t ) = k is a solution of the differential equation 3t 4 3x + dt 4 = 0. Correct Answers: 1.33333333333333 14. (1 pt) Which of the following functions are solutions of the differential equation y 12y + 36y = 0? A. y(x) = 6x B. y(x) = 0 C. y(x) = 6xe6x D. y(x) = x2 e6x E. y(x) = xe6x F. y(x) = e6x G. y(x) = e6x or x. g(y) = E. A curve which at each of its points is perpendicular to the member of the family F that goes through that point is called an orthogonal trajectory to F . Each orthogonal trajectory to F satises the differential equation 1 dy = , dx g(y) where g(y) is the answer to part D. Find a function h(y) such that x = h(y) is the equation of the orthogonal trajectory to F that passes through the point P. h(y) = Correct Answers: 2 * e(6 * (x - 1)) 12 -0.0833333333333333 6*y 1 + (6 /2)*((2 *2 ) - y*y) Correct Answers: BEF 15. (1 pt) Consider the curves in the rst quadrant that have equations y = A exp(6x), where A is a positive constant. Different values of A give different curves. The curves form a family, F . Let P = (1, 2). Let C be the member of the family F that goes through P. A. Let y = f (x) be the equation of C. Find f (x). f (x) = B. Find the slope at P of the tangent to C. slope = C. A curve D is perpendicular to C at P. What is the slope of the tangent to D at the point P? slope = D. Give a formula g(y) for the slope at (x, y) of the member of F that goes through (x, y). The formula should not involve A Generated by the WeBWorK system c WeBWorK Team, Department of Mathematics, University of Rochester 16. (1 pt) The solution of a certain differential equation is of the form y(t ) = a exp(6t ) + b exp(9t ), where a and b are constants. The solution has initial conditions y(0) = 2 and y (0) = 1.
