Program Explanation Given information: The Laplace transform of piecewise continuous function f ( t ) for t ≥ 0 is written as, L { f ( t ) } = F ( s ) = 1 1 − e − p s ∫ 0 p e − s t f ( t ) d t s > 0 Here, function f ( t ) is a periodic function of period p . Calculation: Consider the function f ( t ) as cos k t and therefore, the period p is equivalent to 2 π k . f ( t ) = cos k t = cos k ( 2 π n k + t ) n ∈ ℤ Take Laplace transform of the periodic function f ( t ) and evaluate as shown below. L { f ( t ) } = L { cos k t } = 1 1 − e − ( 2 π k ) s ∫ 0 ( 2 π k ) e − s t ( cos k t ) d t = 1 1 − e − ( 2 π k ) s [ e ( − s ) t ( ( − s ) cos ( k ) t + ( k ) sin ( k ) t ( − s ) 2 + ( k ) 2 ) ] 0 2 π k = 1 1 − e − ( 2 π k ) s [ e − s t ( − s cos k t + k sin k t s 2 + k 2 ) ] 0 2 π k Further, solve the equation as shown below
