how do you do this integral:
∫(t^2)sin⁡(t^3+t^4)√(2t+9t^4+16t^6 )dt

from 0 to 5?

That problem is insane

anonymous · Answer

yah i know

anonymous · Answer

can't use calculator either

anonymous · Answer

i typed it into wolframalpha.com
   it solved the problem but it didnt give the result

anonymous · Answer

I get - 12.01 but after the 01 the number goes even further than that

anonymous · Answer

i dont know if thats the right answer

anonymous · Answer

unless there is another way around it.  original problem is fine the line integran \[\int\limits_{}^{} xsin(y+z)ds

anonymous · Answer

oops
lemme do that again

anonymous · Answer

find the line integral:
$$\int\limits_{}^{} xsin(y+z)ds$$

anonymous · Answer

where x = t^2
y= t^3
z=t^4

$$0\le t \le5$$

anonymous · Answer

the answer should be around 15 too

anonymous · Answer

hmm im not sure

anonymous · Answer

thats what the professor told us.

anonymous · Answer

wow not much of a professor lol I thought professor knew everything

anonymous · Answer

well he told us he wanted us to solve it.  And that the answer was around 15 to kinda help us i guess.  But no clue where to even begin solving that integral

anonymous · Answer

wow i still dont know where to start

anonymous · Answer

yeah same

anonymous · Answer

i think you can use integration by parts here. http://en.wikipedia.org/wiki/Integration_by_parts

anonymous · Answer

umm.. not sure how i would approach it with that

anonymous · Answer

well, I don't remember the procedure now. I just know that these type of integrations can be solved using integration by parts. I think the wikipedia page has the description of how to do it. Sorry I can't be of more help.

ok, thanks anyways.
