You mention to solve 14. and 17.But there are no 17.I am solving 14.
18. Given f(t) = e-at sin(bt) u(t) Using the Laplace transform properties find the Laplace transform of a) g(t) = tf(t) b) m(t) = f(t - 3) this means replace all the occurrences of t with t-3 in f(t)

Solve these two problems. Use the product rule to show that t-derivative of the complex-valued function f(t) = eat (cos bt + i sin bt) = e(a+bi)t is the function f(t) multiplied by a + bi. Use the previous result to find integration formulas for the real and imaginary parts of ſ f(t)dt.
