The solution to the initial value problem y ″ + b y ′ + 4 y = 0 , y ( 0 ) = 1 , y ′ ( 0 ) = 0 for b = 5 , 4 and 2 and sketch the solutions. The solutions to the initial value problem y ″ + b y ′ + 4 y = 0 , y ( 0 ) = 1 , y ′ ( 0 ) = 0 for b = 5 , 4 and 2 are y ( t ) = − 1 3 e − 4 t + 4 3 e − t _ , y ( t ) = e − 2 t + 2 t e − 2 t _ and y ( t ) = e − t cos ( 3 t ) + 1 3 e − t sin ( 3 t ) _ , respectively. Procedure used: Consider the differential equation a y ″ + b y ′ + c y = 0 . The associated auxiliary equation is, a r 2 + b r + c = 0 . Solving the auxiliary equation gives the roots r 1 and r 2 . (a) If the auxiliary equation has distinct real roots r 1 and r 2 , then y ( t ) = c 1 e r 1 t + c 2 e r 2 t is a general solution. (b) If the auxiliary equation has repeated root r , then y ( t ) = c 1 e r t + c 2 t e r t is a general solution. (c) If the auxiliary equation has complex conjugate roots α ± i β , then y ( t ) = c 1 e α t cos β t + c 2 e α t sin β t is a general solution. Calculation: The given initial value problem is y ″ + b y ′ + 4 y = 0 , y ( 0 ) = 1 , y ′ ( 0 ) = 0 . Consider b = 5 . Then, the differential equation will be, y ″ + 5 y ′ + 4 y = 0 . The associated auxiliary equation is r 2 + 5 r + 4 = 0 . Factorize the polynomial r 2 + 5 r + 4 = 0 as follows: r 2 + r + 4 r + 4 = 0 r ( r + 1 ) + 4 ( r + 1 ) = 0 ( r + 4 ) ( r + 1 ) = 0 r = − 4 , − 1 Note that, the roots r = − 4 and r = − 1 are distinct and real. Thus, the general solution will be y ( t ) = c 1 e − 4 t + c 2 e − t . Apply the condition y ( 0 ) = 1 in y ( t ) = c 1 e − 4 t + c 2 e − t , y ( 0 ) = c 1 e − 4 × 0 + c 2 e 0 1 = c 1 ( 1 ) + c 2 ( 1 ) c 1 + c 2 = 1 Differentiate y ( t ) = c 1 e − 4 t + c 2 e − t with respect to t as, y ′ ( t ) = − 4 c 1 e − 4 t − c 2 e − t . Apply the condition y ′ ( 0 ) = 0 in y ′ ( t ) = − 4 c 1 e − 4 t − c 2 e − t , y ′ ( 0 ) = − 4 c 1 e − 4 × 0 − c 2 e 0 0 = − 4 c 1 − c 2 c 2 = − 4 c 1 Substitute c 2 = − 4 c 1 in c 1 + c 2 = 1 , c 1 + c 2 = 1 c 1 − 4 c 1 = 1 − 3 c 1 = 1 c 1 = − 1 3 Thus, c 2 = − 4 c 1 becomes, c 2 = 4 3 . That is, c 1 = − 1 3 and c 2 = 4 3 . The general solution y ( t ) = c 1 e − 4 t + c 2 e − t becomes y ( t ) = − 1 3 e − 4 t + 4 3 e − t . Consider b = 4 . Then, the differential equation will be, y ″ + 4 y ′ + 4 y = 0 . The associated auxiliary equation is r 2 + 4 r + 4 = 0 . Factorize the polynomial r 2 + 4 r + 4 = 0 as follows: r 2 + 2 r + 2 r + 4 = 0 r ( r + 2 ) + 2 ( r + 2 ) = 0 ( r + 2 ) ( r + 2 ) = 0 r = − 2 , − 2 Note that, the roots r = − 2 and r = − 2 are repeated. Thus, the general solution will be y ( t ) = c 1 e − 2 t + c 2 t e − 2 t . Apply the condition y ( 0 ) = 1 in y ( t ) = c 1 e − 2 t + c 2 t e − 2 t , y ( 0 ) = c 1 e − 2 × 0 + c 2 ( 0 ) e − 2 × 0 1 = c 1 ( 1 ) c 1 = 1 Differentiate y ( t ) = c 1 e − 2 t + c 2 t e − 2 t with respect to t to obtain y ′ ( t ) = − 2 c 1 e − 2 t + c 2 ( − 2 t e − 2 t + e − 2 t ) . Apply the condition y ′ ( 0 ) = 0 in y ′ ( t ) = − 2 c 1 e − 2 t + c 2 ( − 2 t e − 2 t + e − 2 t ) , y ′ ( 0 ) = − 2 c 1 e − 2 × 0 + c 2 ( − 2 ( 0 ) e − 2 × 0 + e − 2 × 0 ) 0 = − 2 c 1 + c 2 c 2 = 2 c 1 Substitute c 1 = 1 in c 2 = 2 c 1 to obtain c 2 = 2 . That is, c 1 = 1 and c 2 = 2 . The general solution y ( t ) = c 1 e − 2 t + c 2 t e − 2 t becomes y ( t ) = e − 2 t + 2 t e − 2 t . Consider b = 2 . Then, the differential equation will be, y ″ + 2 y ′ + 4 y = 0 . The associated auxiliary equation is r 2 + 2 r + 4 = 0 . Factorize the polynomial r 2 + 2 r + 4 = 0 using quadratic formula − b ± b 2 − 4 a c 2 a as follows: r = − 2 ± ( 2 ) 2 − 4 ( 1 ) ( 4 ) 2 ( 1 ) = − 2 ± 4 − 16 2 = − 2 ± − 12 2 = − 2 ± 2 3 i 2 ( − 1 = i ) = − 1 ± 3 i That is, r = − 1 ± 3 i . Here, α = − 1 and β = 3 . Thus, the general solution will be y ( t ) = c 1 e − t cos ( 3 t ) + c 2 e − t sin ( 3 t ) . Apply the condition y ( 0 ) = 1 in y ( t ) = c 1 e − t cos ( 3 t ) + c 2 e − t sin ( 3 t ) , y ( 0 ) = c 1 e − ( 0 ) cos ( 3 × 0 ) + c 2 e − ( 0 ) sin ( 3 × 0 ) 1 = c 1 cos ( 0 ) + c 2 sin ( 0 ) 1 = c 1 ( 1 ) + c 2 ( 0 ) c 1 = 1 Differentiate y ( t ) = c 1 e − t cos ( 3 t ) + c 2 e − t sin ( 3 t ) with respect to t as, y ′ ( t ) = c 1 [ − 3 e − t sin ( 3 t ) − e − t cos ( 3 t ) ] + c 2 [ 3 e − t cos ( 3 t ) − e − t sin ( 3 t ) ] = − ( 3 c 1 + c 2 ) e − t sin ( 3 t ) + ( 3 c 2 − c 1 ) e − t cos ( 3 t ) Apply the condition y ′ ( 0 ) = 0 in y ′ ( t ) = − ( 3 c 1 + c 2 ) e − t sin ( 3 t ) + ( 3 c 2 − c 1 ) e − t cos ( 3 t ) , y ′ ( 0 ) = − ( 3 c 1 + c 2 ) e 0 sin ( 3 × 0 ) + ( 3 c 2 − c 1 ) e 0 cos ( 3 × 0 ) 0 = − ( 3 c 1 + c 2 ) sin ( 0 ) + ( 3 c 2 − c 1 ) cos ( 0 ) 0 = ( 3 c 2 − c 1 ) c 1 = 3 c 2 c 2 = c 1 3 Substitute c 1 = 1 in c 2 = c 1 3 to obtain c 2 = 1 3 . That is, c 1 = 1 and c 2 = 1 3 . The general solution y ( t ) = c 1 e − t cos ( 3 t ) + c 2 e − t sin ( 3 t ) becomes y ( t ) = e − t cos ( 3 t ) + 1 3 e − t sin ( 3 t ) . Therefore, the solutions to the initial value problem y ″ + b y ′ + 4 y = 0 , y ( 0 ) = 1 , y ′ ( 0 ) = 0 for b = 5 , 4 and 2 are y ( t ) = − 1 3 e − 4 t + 4 3 e − t _ , y ( t ) = e − 2 t + 2 t e − 2 t _ and y ( t ) = e − t cos ( 3 t ) + 1 3 e − t sin ( 3 t ) _ , respectively. Use online graphing calculator and graph the solutions to the initial value problem y ″ + b y ′ + 4 y = 0 , y ( 0 ) = 1 , y ′ ( 0 ) = 0 for b = 5 , 4 and 2 as shown below in Figure 1. From Figure 1, it is observed that for b = 5 , 4 and 2 , the solution tends to 0 as t → ∞ . This can be explained due to the presence of negative powers of the exponential.

(c) If the auxiliary equation has complex conjugate roots α ± i β , then y ( t ) = c 1 e α t cos β t + c 2 e α t sin β t is a general solution. Calculation: The given initial value problem is y ″ + b y ′ + 4 y = 0 , y ( 0 ) = 1 , y ′ ( 0 ) = 0 . Consider b = 5 . Then, the differential equation will be, y ″ + 5 y ′ + 4 y = 0 . The associated auxiliary equation is r 2 + 5 r + 4 = 0 . Factorize the polynomial r 2 + 5 r + 4 = 0 as follows: r 2 + r + 4 r + 4 = 0 r ( r + 1 ) + 4 ( r + 1 ) = 0 ( r + 4 ) ( r + 1 ) = 0 r = − 4 , − 1 Note that, the roots r = − 4 and r = − 1 are distinct and real. Thus, the general solution will be y ( t ) = c 1 e − 4 t + c 2 e − t . Apply the condition y ( 0 ) = 1 in y ( t ) = c 1 e − 4 t + c 2 e − t , y ( 0 ) = c 1 e − 4 × 0 + c 2 e 0 1 = c 1 ( 1 ) + c 2 ( 1 ) c 1 + c 2 = 1 Differentiate y ( t ) = c 1 e − 4 t + c 2 e − t with respect to t as, y ′ ( t ) = − 4 c 1 e − 4 t − c 2 e − t . Apply the condition y ′ ( 0 ) = 0 in y ′ ( t ) = − 4 c 1 e − 4 t − c 2 e − t , y ′ ( 0 ) = − 4 c 1 e − 4 × 0 − c 2 e 0 0 = − 4 c 1 − c 2 c 2 = − 4 c 1 Substitute c 2 = − 4 c 1 in c 1 + c 2 = 1 , c 1 + c 2 = 1 c 1 − 4 c 1 = 1 − 3 c 1 = 1 c 1 = − 1 3 Thus, c 2 = − 4 c 1 becomes, c 2 = 4 3 . That is, c 1 = − 1 3 and c 2 = 4 3 . The general solution y ( t ) = c 1 e − 4 t + c 2 e − t becomes y ( t ) = − 1 3 e − 4 t + 4 3 e − t . Consider b = 4 . Then, the differential equation will be, y ″ + 4 y ′ + 4 y = 0 . The associated auxiliary equation is r 2 + 4 r + 4 = 0 . Factorize the polynomial r 2 + 4 r + 4 = 0 as follows: r 2 + 2 r + 2 r + 4 = 0 r ( r + 2 ) + 2 ( r + 2 ) = 0 ( r + 2 ) ( r + 2 ) = 0 r = − 2 , − 2 Note that, the roots r = − 2 and r = − 2 are repeated. Thus, the general solution will be y ( t ) = c 1 e − 2 t + c 2 t e − 2 t . Apply the condition y ( 0 ) = 1 in y ( t ) = c 1 e − 2 t + c 2 t e − 2 t , y ( 0 ) = c 1 e − 2 × 0 + c 2 ( 0 ) e − 2 × 0 1 = c 1 ( 1 ) c 1 = 1 Differentiate y ( t ) = c 1 e − 2 t + c 2 t e − 2 t with respect to t to obtain y ′ ( t ) = − 2 c 1 e − 2 t + c 2 ( − 2 t e − 2 t + e − 2 t ) . Apply the condition y ′ ( 0 ) = 0 in y ′ ( t ) = − 2 c 1 e − 2 t + c 2 ( − 2 t e − 2 t + e − 2 t ) , y ′ ( 0 ) = − 2 c 1 e − 2 × 0 + c 2 ( − 2 ( 0 ) e − 2 × 0 + e − 2 × 0 ) 0 = − 2 c 1 + c 2 c 2 = 2 c 1 Substitute c 1 = 1 in c 2 = 2 c 1 to obtain c 2 = 2 . That is, c 1 = 1 and c 2 = 2 . The general solution y ( t ) = c 1 e − 2 t + c 2 t e − 2 t becomes y ( t ) = e − 2 t + 2 t e − 2 t . Consider b = 2 . Then, the differential equation will be, y ″ + 2 y ′ + 4 y = 0 . The associated auxiliary equation is r 2 + 2 r + 4 = 0 . Factorize the polynomial r 2 + 2 r + 4 = 0 using quadratic formula − b ± b 2 − 4 a c 2 a as follows: r = − 2 ± ( 2 ) 2 − 4 ( 1 ) ( 4 ) 2 ( 1 ) = − 2 ± 4 − 16 2 = − 2 ± − 12 2 = − 2 ± 2 3 i 2 ( − 1 = i ) = − 1 ± 3 i That is, r = − 1 ± 3 i . Here, α = − 1 and β = 3 . Thus, the general solution will be y ( t ) = c 1 e − t cos ( 3 t ) + c 2 e − t sin ( 3 t ) .
