A function f is periodic with period T >0 if and only if for all t we have f(t+T)=f(t). 2. If f is bounded, piecewise continuous and periodic with period T, then LWe use t as the independent variable for f because in applications the Laplace transform is usually applied to functions of time. The Laplace transform can be viewed as an operator L that transforms the function f = f(t) into the function F = F(s). Thus, Equation 8.1.3 can be expressed as. F = L(f).You can just do some pattern matching right here. If a is equal to 2, then this would be the Laplace Transform of sine of 2t. So it's minus 1/3 times sine of 2t plus 2/3 times-- this is the …
