## anonymous one year ago Solve the integral

1. anonymous

whats the question

2. anonymous

$\int\limits_{?}^{?}(\sqrt{1-x})\div \sqrt{x}$

3. anonymous

|dw:1443535046366:dw|

4. anonymous

ok give me a sec what subject is it

5. anonymous

calc 2

6. anonymous

i dont understand why the use of trig identity since its not in the form of a^2 and u^2

7. ParthKohli

but you can make it so

8. anonymous

x3+2 1−x−−−−−√ 2x+C

9. ParthKohli

$1 - \sin^2 x = \cos^2 x$which enables us to clear out the square-root.

10. anonymous

go with that mine screwed up

11. ParthKohli

shouldn't really think of it as "forms" - try to think why those forms are altered when you substitute a trigonometric function.

12. anonymous

ok let me try to do it then

13. anonymous

|dw:1443535393664:dw|

14. anonymous

does this look like a good start

15. ParthKohli

$x = \sin ^2 \theta$

16. anonymous

ok

17. ParthKohli

remember - you want to clear the square-root out.

18. ParthKohli

i have two gentlemen here who have way more experience at integration

19. anonymous

ok.. any help is welcome

23. anonymous

can some plz check this out

24. anonymous

i havent converted it back to to xs yet

25. ParthKohli

looks good I think

26. anonymous

alright thanks 4 the awesome help
