Method of undetermined coefficients: A particular solution to the differential equation a y ″ + b y ′ + c y = C t m e r t , where m is a nonnegative integer, is of the form y p ( t ) = t s ( A m t m + ⋯ + A 1 t + A 0 ) e r t with: (i) s = 0 , if r is not a root of the associated auxiliary equation; (ii) s = 1 , if r is a simple root of the associated auxiliary equation; (iii) s = 2 , if r is a double root of the associated auxiliary equation. A particular solution to the differential equation a y ″ + b y ′ + c y = P m ( t ) e α t cos β t + Q n ( t ) e α t sin β t , β ≠ 0 , where P m ( t ) and Q n ( t ) is a polynomial of degree m and n respectively, is of the form y p ( t ) = t s ( A k t k + ⋯ + A 1 t + A 0 ) e α t cos β t + t s ( B k t k + ⋯ + B 1 t + B 0 ) e α t sin β t , where k is the larger of m and n : (i) s = 0 , if α + i β is not a root of the associated auxiliary equation; (ii) s = 1 , if α + i β is a root of the associated auxiliary equation. 2. Method of variation of parameters: The following are the steps to obtain a particular solution to a y ″ + b y ′ + c y = f . (i) Find two linearly independent solutions { y 1 ( t ) , y 2 ( t ) } to the corresponding homogenous equation and take y p ( t ) = v 1 ( t ) y 1 ( t ) + v 2 ( t ) y 2 ( t ) . (ii) Determine v 1 ( t ) and v 2 ( t ) by solving the below system for v ′ 1 ( t ) and v ′ 2 ( t ) and integrating. y 1 v ′ 1 + y 2 v ′ 2 = 0 y ′ 1 v ′ 1 + y ′ 2 v ′ 2 = f a This can be simplified using Cramer’s rule as, v ′ 1 ( t ) = − f ( t ) y 2 ( t ) a [ y 1 ( t ) y ′ 2 ( t ) − y ′ 1 ( t ) y 2 ( t ) ] and v ′ 2 ( t ) = f ( t ) y 1 ( t ) a [ y 1 ( t ) y ′ 2 ( t ) − y ′ 1 ( t ) y 2 ( t ) ] (iii) Substitute v 1 ( t ) and v 2 ( t ) into the expression for y p ( t ) to obtain a particular solution. 3. Superposition principle: If y 1 is a solution to the differential equation a y ″ + b y ′ + c y = f 1 ( t ) and y 2 is a solution to a y ″ + b y ′ + c y = f 2 ( t ) , then for any constants k 1 and k 2 , the function k 1 y 1 + k 2 y 2 is a solution to the differential equation a y ″ + b y ′ + c y = k 1 f 1 ( t ) + k 2 f 2 ( t ) . Calculation: The given differential equation is, 1 2 y ″ + 2 y = tan 2 t − 1 2 e t . The corresponding auxiliary equation is 1 2 r 2 + 2 = 0 . Simplify 1 2 r 2 + 2 = 0 as, r 2 + 4 = 0 r 2 = − 4 r = ± − 4 r = ± 2 i ( ∵ i = − 1 ) That is, the roots are r 1 = 2 i and r 2 = − 2 i . Here, α = 0 and β = 2 . Thus, the general solution for the homogenous equation is y ( t ) = c 1 cos 2 t + c 2 sin 2 t . The differential equation 1 2 y ″ + 2 y = tan 2 t − 1 2 e t is split into equations, 1 2 y ″ + 2 y = tan 2 t and 1 2 y ″ + 2 y = − 1 2 e t . The solution to 1 2 y ″ + 2 y = tan 2 t is obtained using variation of parameters, the solution to 1 2 y ″ + 2 y = − 1 2 e t is obtained using undetermined coefficients and the superposition principle is applied to combine both solutions. Obtain the solution to 1 2 y ″ + 2 y = − 1 2 e t using the method of undetermined coefficients as follows: Since the RHS of the differential equation 1 2 y ″ + 2 y = − 1 2 e t is − 1 2 e t . The particular solution will be of the form y p ( t ) = A e t . The second derivative of y p ( t ) = A e t is y ″ p ( t ) = A e t . Thus, 1 2 y ″ + 2 y for y p will be, 1 2 A e t + 2 A e t = 5 2 A e t . Set 5 2 A e t = − 1 2 e t and comparing the coefficients will results in 5 2 A = − 1 2 . On simplification, A = − 1 5 . Thus, the particular solution y p ( t ) = A e t becomes y p ( t ) = − 1 5 e t . That is, the solution to 1 2 y ″ + 2 y = − 1 2 e t using the method of undetermined coefficients is y p ( t ) = − 1 5 e t . Obtain the solution to 1 2 y ″ + 2 y = tan 2 t is obtained using variation of parameters as follows: Since the general solution for the homogenous equation 1 2 y ″ + 2 y = 0 is y ( t ) = c 1 cos 2 t + c 2 sin 2 t , the two independent solutions are cos 2 t and sin 2 t . Let y 1 ( t ) = cos 2 t and y 2 ( t ) = sin 2 t . Then, y ′ 1 ( t ) = − 2 sin 2 t and y ′ 2 ( t ) = 2 cos 2 t . Set the particular solution y p ( t ) = v 1 ( t ) y 1 ( t ) + v 2 ( t ) y 2 ( t ) as, y p ( t ) = v 1 ( t ) cos 2 t + v 2 ( t ) sin 2 t . Obtain the Wronskian y 1 ( t ) y ′ 2 ( t ) − y ′ 1 ( t ) y 2 ( t ) as, W = | cos 2 t sin 2 t − 2 sin 2 t 2 cos 2 t | = 2 cos 2 2 t + 2 sin 2 2 t = 2 Compare 1 2 y ″ + 2 y = tan 2 t with the general equation form a y ″ + b y ′ + c y = f to obtain a = 1 2 , b = 0 , c = 2 and f = tan 2 t . The value of v ′ 1 ( t ) = − f ( t ) y 2 ( t ) a [ y 1 ( t ) y ′ 2 ( t ) − y ′ 1 ( t ) y 2 ( t ) ] becomes, v ′ 1 ( t ) = ( − tan 2 t ) sin 2 t ( 1 2 ) [ 2 ] = − tan 2 t sin 2 t The value of v ′ 2 ( t ) = f ( t ) y 1 ( t ) a [ y 1 ( t ) y ′ 2 ( t ) − y ′ 1 ( t ) y 2 ( t ) ] becomes, v ′ 2 ( t ) = ( tan 2 t ) ( cos 2 t ) ( 1 2 ) [ 2 ] = ( sin 2 t cos t ) ( cos 2 t ) = sin 2 t Integrating v ′ 1 ( t ) = − tan 2 t sin 2 t gives, v 1 ( t ) = ∫ v 1 ′ ( t ) d t = − ∫ tan 2 t sin 2 t d t = − ∫ sin 2 2 t cos 2 t d t = − ∫ 1 − cos 2 2 t cos 2 t d t Simplify further as, v 1 ( t ) = − ∫ 1 cos 2 t d t + ∫ cos 2 t d t = − ∫ sec 2 t d t + ∫ cos 2 t d t = − 1 2 ln | sec 2 t + tan 2 t | + 1 2 sin 2 t + C 1 Integrating v ′ 2 ( t ) = sin 2 t gives, v 2 ( t ) = ∫ v ′ 2 ( t ) = ∫ sin 2 t d t = − 1 2 cos 2 t + C 2 Since particular solution is to be obtained, take both C 1 and C 2 zero for simplicity. That is, v 1 ( t ) = − 1 2 ln | sec 2 t + tan 2 t | + 1 2 sin 2 t and v 2 ( t ) = − 1 2 cos 2 t . Thus, the particular solution y p ( t ) = v 1 ( t ) cos 2 t + v 2 ( t ) sin 2 t becomes, y p ( t ) = [ − 1 2 ln | sec 2 t + tan 2 t | + 1 2 sin 2 t ] cos 2 t + ( − 1 2 cos 2 t ) sin 2 t = − 1 2 cos 2 t ln | sec 2 t + tan 2 t | + 1 2 cos 2 t sin 2 t − 1 2 cos 2 t sin 2 t = − 1 2 cos 2 t ln | sec 2 t + tan 2 t | That is, the solution to 1 2 y ″ + 2 y = tan 2 t using the method of variation of parameters is y p ( t ) = − 1 2 cos 2 t ln | sec 2 t + tan 2 t | . By superposition principle, the particular solution to 1 2 y ″ + 2 y = tan 2 t − 1 2 e t will be, y p ( t ) = − 1 2 cos 2 t ln | sec 2 t + tan 2 t | − 1 5 e t . Combine the general solution y ( t ) = c 1 cos 2 t + c 2 sin 2 t of the corresponding homogenous equation and the particular solution y p ( t ) = − 1 2 cos 2 t ln | sec 2 t + tan 2 t | − 1 5 e t to obtain y ( t ) = c 1 cos 2 t + c 2 sin 2 t − 1 2 cos 2 t ln | sec 2 t + tan 2 t | − 1 5 e t . Therefore, the general solution to the differential equation 1 2 y ″ + 2 y = tan 2 t − 1 2 e t is y ( t ) = c 1 cos 2 t + c 2 sin 2 t − 1 2 cos 2 t ln | sec 2 t + tan 2 t | − 1 5 e t _ .

Method of variation of parameters: The following are the steps to obtain a particular solution to a y ″ + b y ′ + c y = f . (i) Find two linearly independent solutions { y 1 ( t ) , y 2 ( t ) } to the corresponding homogenous equation and take y p ( t ) = v 1 ( t ) y 1 ( t ) + v 2 ( t ) y 2 ( t ) . (ii) Determine v 1 ( t ) and v 2 ( t ) by solving the below system for v ′ 1 ( t ) and v ′ 2 ( t ) and integrating. y 1 v ′ 1 + y 2 v ′ 2 = 0 y ′ 1 v ′ 1 + y ′ 2 v ′ 2 = f a This can be simplified using Cramer’s rule as, v ′ 1 ( t ) = − f ( t ) y 2 ( t ) a [ y 1 ( t ) y ′ 2 ( t ) − y ′ 1 ( t ) y 2 ( t ) ] and v ′ 2 ( t ) = f ( t ) y 1 ( t ) a [ y 1 ( t ) y ′ 2 ( t ) − y ′ 1 ( t ) y 2 ( t ) ] (iii) Substitute v 1 ( t ) and v 2 ( t ) into the expression for y p ( t ) to obtain a particular solution. 3. Superposition principle: If y 1 is a solution to the differential equation a y ″ + b y ′ + c y = f 1 ( t ) and y 2 is a solution to a y ″ + b y ′ + c y = f 2 ( t ) , then for any constants k 1 and k 2 , the function k 1 y 1 + k 2 y 2 is a solution to the differential equation a y ″ + b y ′ + c y = k 1 f 1 ( t ) + k 2 f 2 ( t ) . Calculation: The given differential equation is, 1 2 y ″ + 2 y = tan 2 t − 1 2 e t . The corresponding auxiliary equation is 1 2 r 2 + 2 = 0 . Simplify 1 2 r 2 + 2 = 0 as, r 2 + 4 = 0 r 2 = − 4 r = ± − 4 r = ± 2 i ( ∵ i = − 1 ) That is, the roots are r 1 = 2 i and r 2 = − 2 i . Here, α = 0 and β = 2 . Thus, the general solution for the homogenous equation is y ( t ) = c 1 cos 2 t + c 2 sin 2 t . The differential equation 1 2 y ″ + 2 y = tan 2 t − 1 2 e t is split into equations, 1 2 y ″ + 2 y = tan 2 t and 1 2 y ″ + 2 y = − 1 2 e t . The solution to 1 2 y ″ + 2 y = tan 2 t is obtained using variation of parameters, the solution to 1 2 y ″ + 2 y = − 1 2 e t is obtained using undetermined coefficients and the superposition principle is applied to combine both solutions. Obtain the solution to 1 2 y ″ + 2 y = − 1 2 e t using the method of undetermined coefficients as follows: Since the RHS of the differential equation 1 2 y ″ + 2 y = − 1 2 e t is − 1 2 e t . The particular solution will be of the form y p ( t ) = A e t . The second derivative of y p ( t ) = A e t is y ″ p ( t ) = A e t . Thus, 1 2 y ″ + 2 y for y p will be, 1 2 A e t + 2 A e t = 5 2 A e t . Set 5 2 A e t = − 1 2 e t and comparing the coefficients will results in 5 2 A = − 1 2 . On simplification, A = − 1 5 . Thus, the particular solution y p ( t ) = A e t becomes y p ( t ) = − 1 5 e t . That is, the solution to 1 2 y ″ + 2 y = − 1 2 e t using the method of undetermined coefficients is y p ( t ) = − 1 5 e t . Obtain the solution to 1 2 y ″ + 2 y = tan 2 t is obtained using variation of parameters as follows: Since the general solution for the homogenous equation 1 2 y ″ + 2 y = 0 is y ( t ) = c 1 cos 2 t + c 2 sin 2 t , the two independent solutions are cos 2 t and sin 2 t . Let y 1 ( t ) = cos 2 t and y 2 ( t ) = sin 2 t . Then, y ′ 1 ( t ) = − 2 sin 2 t and y ′ 2 ( t ) = 2 cos 2 t . Set the particular solution y p ( t ) = v 1 ( t ) y 1 ( t ) + v 2 ( t ) y 2 ( t ) as, y p ( t ) = v 1 ( t ) cos 2 t + v 2 ( t ) sin 2 t . Obtain the Wronskian y 1 ( t ) y ′ 2 ( t ) − y ′ 1 ( t ) y 2 ( t ) as, W = | cos 2 t sin 2 t − 2 sin 2 t 2 cos 2 t | = 2 cos 2 2 t + 2 sin 2 2 t = 2 Compare 1 2 y ″ + 2 y = tan 2 t with the general equation form a y ″ + b y ′ + c y = f to obtain a = 1 2 , b = 0 , c = 2 and f = tan 2 t .

That is, v 1 ( t ) = − 1 2 ln | sec 2 t + tan 2 t | + 1 2 sin 2 t and v 2 ( t ) = − 1 2 cos 2 t . Thus, the particular solution y p ( t ) = v 1 ( t ) cos 2 t + v 2 ( t ) sin 2 t becomes, y p ( t ) = [ − 1 2 ln | sec 2 t + tan 2 t | + 1 2 sin 2 t ] cos 2 t + ( − 1 2 cos 2 t ) sin 2 t = − 1 2 cos 2 t ln | sec 2 t + tan 2 t | + 1 2 cos 2 t sin 2 t − 1 2 cos 2 t sin 2 t = − 1 2 cos 2 t ln | sec 2 t + tan 2 t | That is, the solution to 1 2 y ″ + 2 y = tan 2 t using the method of variation of parameters is y p ( t ) = − 1 2 cos 2 t ln | sec 2 t + tan 2 t | . By superposition principle, the particular solution to 1 2 y ″ + 2 y = tan 2 t − 1 2 e t will be, y p ( t ) = − 1 2 cos 2 t ln | sec 2 t + tan 2 t | − 1 5 e t .
