: C I Ii Using The Convolution Theorem Show That 1 1 L S B 2b Sin Bt Bt Cos Br 26 Hence Solve The Diff 1 (40.32 KiB) Viewed 31 times

(c) (i) (ii) Using the convolution theorem, show that 1 1 L'{(s² + b)²}=2b (sin bt-bt cos br). 26³ Hence, solve the differential equation d²y dt² given that y and dy dx - 4y = t cos 2t. are both zero when t = 0. (7 marks) (6 marks)
