## anonymous 5 years ago can someone help with my cal 3? i posted a question and im still stuck.

1. anonymous

yeah whats up

2. anonymous

ok thanks im going to type it now...

3. anonymous

$\int\limits_{0}^{6}\int\limits_{?}^{?}$

4. anonymous

$\int\limits_{0}^{5}\int\limits_{0}^{y}(siny/y)$

5. anonymous

dx dy ?

6. anonymous

dxdy

7. anonymous

with respect to dx, the integral of sin y/y is just a constant so you get [ sin y/y *x ] and you integrate from y to 0

8. anonymous

ok so it would be integrate from 5 to 0 (siny^2/2)?

9. anonymous

no you didnt plug in y to 0 for x

10. anonymous

integral [ sin y/y [ y - 0] dy

11. anonymous

when you plug y in for x will the bottom y cancel out?

12. anonymous

$\int\limits_{0}^{y}$

13. anonymous

im lost

14. anonymous

its not hard

15. anonymous

this latex thing is killing me

16. anonymous

what?

17. anonymous

it can you please work it out for me?

18. anonymous

$\int\limits_{0}^{5}\int\limits_{y}^{0} siny/y dx dy =$

19. anonymous

forget it, im sick of this , find someone else. this latex is retarded

20. anonymous

since siny/y is a constant wouldn't you multiply it times x and then plug y in for x?

21. anonymous

yes

22. anonymous

23. anonymous

$\int\limits_{0}^{5}$$\int\limits_{0}^{y}$

24. anonymous

$\int\limits_{?}^{?}\int\limits_{?}^{?}$

25. anonymous

ok after i did that i got $\int\limits_{0}^{5}sinydy$

26. anonymous

anyone?

this is baby calculus, cmon
