5. H(t) = sin(t)

8. R(t) = -(1/t)

12. F(t) = (2/3)t^3 + (3/4)t^4 + (4/5)t^5

18. R(t) = e^t + 5e^(5t)

19. Q(t) = (1/3)t^3 + t^2 + t

23. H(x) = (1/4)x^4 ?(1/2)x^2 + C

26. F(z) = (1/2)z^2 + e^z + C

31. P(t) = 2t^(1/2) + C

34. F(x) = x^2

38. F(x) = (2/3)x^(3/2)

41. (5/2)x^2 + C

43. -cos*theta + C

45. (1/3)t^3 ?(1/t) + C

48. -(4/t) + C

51. 5e^z + C

55. (2/5)t^(5/2) ?2t^(-1/2) + C

58. (1/(e^z)) + C

The derivative of this expression would be - 1 / e^z, not e^z.

I need to see your work and your reasoning, not just your answers. On the Assignments page you are instructed to run the Query program, which asks questions about selected problems:

"When you have completed the entire assignment run query_cal2_thru_16_4th_edition.exe and submit the SEND file it creates using the Submit Work Form."

This is how you need to submit your work.

Fortunately I happen to have my copy of the book at this location and was able to look over a good sampling of your answers. Your answers appear to be good and it's clear that you're in good shape on this section. See my notes on #58, though.
