div means goes off into infinity right?
if it integrates to a value its convergent
cosx comes from sinx 6 sinx from 0 to inf well, im sure sinx bounces back and forth so it has no value at infinity ... but lets check the wolf just in case the althiemers is rearing up :)
http://www.wolframalpha.com/input/?i=integrate+6cos%28x%29+from+0+to+infinity doesnt converge, must diverge then
yeah, same thing I got, but I also got that the theta one diverges :/
the last one; is that sin(10t) dt ? or sin(10) t dt
sin10(theta) d(theta) I believe
in either case, it doesnt converge either ... according to the wolf. so in this case, is there a difference definition of divergent than the one of used to seeing?
DNE and divergent might be different ideas
Well, can't you say it diverges by TFD?
test for divergence? perhaps
the last 2 definantly diverge; maybe its a program error?
That really sucks of me then lol, I can only choose one...
who grades it?
Automatically, by the computer
whats your grade at the moment :)
Lol, its about 93,ish
I'll try taking a screen shot and email it to the professor, if I miss it maybe he'll just give me the points :P
might just have to cross your fingers and click next ;)
thats possible too
Hope he's in a good mood, but thanks for the help!
good luck ..
