Which of the following integrals are divergent? There are 3 functions there and I believe that the last 2 both diverge, am I doing something wrong? Because I can only choose 1 answer,

    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 :/

    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?
