The value of the function f ( t ) if the Laplace transform of f is L ( f ) = 5.5 ( s + 1.5 ) ( s − 4 ) . The function f ( t ) is f ( t ) = e 4 t − e − 1.5 t _ . Definition used: The convolution of the functions f and g , denoted by the standard notation f ∗ g and it is defined by the integral h ( t ) = ( f ∗ g ) ( t ) = ∫ 0 t f ( τ ) g ( t − τ ) d τ . Theorem used: “If two functions f and g satisfy the assumptions in the existence theorem, so that their transformation F and G exist, the product H = F G is the transform of h given by h ( t ) = ( f ∗ g ) ( t ) = ∫ 0 t f ( τ ) g ( t − τ ) d τ ”. Calculation: Given that, the Laplace transform of f is L ( f ) = 5.5 ( s + 1.5 ) ( s − 4 ) . It can be written as, L ( f ) = ( 5.5 ) ⋅ ( 1 ( s + 1.5 ) ) ⋅ ( 1 ( s − 4 ) ) . Let 1 ( s + 1.5 ) be L ( g ) = ( 1 ( s + 1.5 ) ) and 1 ( s − 4 ) be L ( k ) = ( 1 ( s − 4 ) ) . Thus, the given function can be written as, L ( f ) = ( 5.5 ) ⋅ L ( g ) ⋅ L ( k ) . Now compute the functions g ( t ) and k ( t ) as follows. Take inverse transform on both sides of L ( g ) = ( 1 ( s + 1.5 ) ) as follows. L − 1 { L ( g ) } = L − 1 { 1 s + 1.5 } g ( t ) = e − 1.5 t Take inverse transform on both sides of L ( k ) = ( 1 ( s − 4 ) ) as follows. L − 1 { L ( k ) } = L − 1 { 1 s − 4 } k ( t ) = e 4 t Here, it is observed that g ( τ ) = e − 1.5 τ and k ( t − τ ) = e 4 ( t − τ ) . Now by the convolution theorem, the function f ( t ) is f ( t ) = 5.5 [ ∫ 0 t g ( τ ) k ( t − τ ) d τ ] . Now compute the function f ( t ) as follows. f ( t ) = 5.5 ∫ 0 t g ( τ ) k ( t − τ ) d τ = 5.5 ∫ 0 t ( e − 1.5 τ ) ( e 4 ( t − τ ) ) d τ = 5.5 ∫ 0 t ( e − 1.5 τ ) ( e 4 t − 4 τ ) d τ = 5.5 ∫ 0 t ( e − 1.5 τ + 4 t − 4 τ ) d τ Simplify further as follows. f ( t ) = 5.5 ∫ 0 t ( e − 5.5 τ + 4 t ) d τ = 5.5 e 4 t ∫ 0 t ( e − 5.5 τ ) d τ = 5.5 e 4 t [ e − 5.5 τ − 5.5 ] 0 t = 5.5 e 4 t [ e − 5.5 t − 1 − 5.5 ] On further simplification. f ( t ) = 5.5 e 4 t [ e − 5.5 t − 1 − 5.5 ] = − e 4 t [ e − 5.5 t − 1 ] = e 4 t − e 4 t − 5.5 t = e 4 t − e − 1.5 t Thus, the function f ( t ) is f ( t ) = e 4 t − e − 1.5 t _ .
