plz solve only part 28 and 31 within 30-40 mins I'll upvote your answer
In Problems 19-36 use Theorem 7.1.1 to find L{f(1)}.
19. f(1) = 2r*
20. f(1) = 1
21. f(1) = 41 – 10
22. f(1) = 71 + 3
23. f(1) = r? + 61 – 3
24. f(1) = -412 + 16t + 9
26. f(1) = (21 – 1)
28. f(1) = r² – e-1 + 5
25. f(1) = (t + 1)'
27. f(1) = 1 + e*'
29. f(1) = (1 + e2)2
30. f(1) = (e' – e¯)?
31. f(1) = 41² – 5 sin 31
32. f(1) = cos 5t + sin 21
