11. experimentX Group Title

|dw:1349888513102:dw|

12. precal Group Title

|dw:1349888712658:dw|ok sorry, I thought you were completing the square, interesting (have not seen anyone rewrite a variable before)

13. experimentX Group Title

yes!!

14. experimentX Group Title

|dw:1349888984719:dw| how do you do that?

15. chakshu Group Title

still cant get how to solve the divison??

16. experimentX Group Title

@chakshu which division?

17. precal Group Title

|dw:1349889100844:dw|did we not drop a negative sign since the original problem is -x

18. experimentX Group Title

oh yes ... for now how do you do the first part of that integration?

19. precal Group Title

that is a u sub problem

20. chakshu Group Title

yes how u solve the integeration in divs form?

21. precal Group Title

|dw:1349889222108:dw|

22. experimentX Group Title

all right!! |dw:1349889308466:dw|

24. experimentX Group Title

|dw:1349889386653:dw| yep!! can yo do that?

25. precal Group Title

is that a trig sub?

26. experimentX Group Title

yep!!

27. precal Group Title

looking at my integral tables to see which one it is, need a moment or two

28. experimentX Group Title

this is one of nice and easy form ... you should remember this for shortcut ... although you can do this using trig subs |dw:1349889536072:dw|

29. precal Group Title

34. precal Group Title

|dw:1349889918864:dw|

35. precal Group Title

ok is that it?

36. experimentX Group Title

for the last part |dw:1349889905103:dw|

37. experimentX Group Title
