Question

Find the laplace transform of the function:
f(t)=2 if 0 <= t < 3; f(t)=0 if t >= 3.

Answer 1

u know that\[L(f)=\int_0^\infty f(t) e^{-st} dt\]and u can write for this particular f\[L(f)=\int_0^3 2 \times e^{-st} dt+\int_3^\infty 0 \times e^{-st} dt=2\int_0^3 e^{-st} dt\]

Answer 2

last integral is easy to calculate :)
