## anonymous 5 years ago how would you intergate sqrt{s+t}ds dt

1. anonymous

there shouldn't be 2 d's?

2. anonymous

Never seen that before.

3. anonymous

$\int\limits_{0}^{1} \int\limits_{0}^{1} \sqrt{s+t} ds dt$

4. anonymous

Oh you take the intergral of the inside and then take the interal of the whole thing..

5. anonymous

oh no but it is both terms... hmm..

6. anonymous

It's some 3D plot http://www.wolframalpha.com/input/?i=integrate+sqrt%28s%2Bt%29ds+dt+

7. anonymous

so would you set one as a contasnt then intgrate to s then plug in and solve and integrate to t, but i don"t remenber how to intergrate a sqrt

8. anonymous

you just write the sqrt as x^1/2, and then you have 2/3x^3/2

9. anonymous

I have no idea how you would integrate that tho.. there are 2 variables... you would need an equation to define s in term of t or vise versa... I think the problem is from multi variable calc, which I am not familiar with at all.

10. anonymous

it is, but thank you anyway

11. anonymous

are you in college?

12. anonymous

yes it is cacl 4 homework problem

13. anonymous

i see i see... im taking calc 3 next quarter.. and probably calc 4 after that.

14. anonymous

so your doing all the sequnces and series stuff, and polar stuff now then or no

15. anonymous

Im taking the BC test in like a week, so I'm doing all that now.

16. anonymous

whats is bc, your calc 2 must be different

17. anonymous

calc3

18. anonymous

Its the high school version of calc... BC is calc 1 and 2. calc 3 is in college.

19. anonymous

okay, yea i did that same stuff in high school, still had to take it over in once i got to college, kinda sucked
