Best ResponseYou've already chosen the best response.0Is this lim as r approaches 0? All you need to do for this one is plug 0 into all r's. r^2*ln(r^2)? (0)^2*ln((0)^2) = DNE

Best ResponseYou've already chosen the best response.0The limit is as r approaches 0+, but the answer is supposed to be 0 and I just can't prove it...

Best ResponseYou've already chosen the best response.0This is an indeterminate of the form 0^(0) so try using L'Hopitals Rule

Best ResponseYou've already chosen the best response.0my mistake its actually (infinity)^(0) but still and indeterminate, so L'Hopitals should work

Best ResponseYou've already chosen the best response.0does anyone want the method

Best ResponseYou've already chosen the best response.0can nobody please explain to me how to apply de l'hopital to this? or any other method?

Best ResponseYou've already chosen the best response.0hello friend, it was my mistake. I thought it was r^2/ln(r^2)?

anonymous

Best ResponseYou've already chosen the best response.0else the answer is infinity. I can explain you the L'hospital rule

Best ResponseYou've already chosen the best response.0If you get 0^0 form or 0/0 then you can differentiate the given function which is r^2*ln(r^2) here

Best ResponseYou've already chosen the best response.0when u find d/dr(r^2*ln(r^2) the answer is 2rln(r^2)+2r

Best ResponseYou've already chosen the best response.0this is again of the form 0^0 therefore u differentiate it again

Best ResponseYou've already chosen the best response.0so u wud get 2ln(r^2)+6 which is again log0=infinity, when r tends to 0

anonymous

Best ResponseYou've already chosen the best response.0again u differentiate it, u wud get 4/r when r tends to zero, 4/r wud tend to infinity as any number divided by 0 is infinity

anonymous

Best ResponseYou've already chosen the best response.0therefore u wud get an infinity

anonymous

Best ResponseYou've already chosen the best response.0but wouldn't the limit of 2ln(r^2)+ 6 be infinity?

Best ResponseYou've already chosen the best response.0so u can again differentiate

anonymous

Best ResponseYou've already chosen the best response.0when u differentiate it again and again and again, u r getting only infinity.differentiating means breaking into smaller parts. But when we add this delta x and delta y again and again we are still getting infinity so the answer wud be infinity

anonymous

Best ResponseYou've already chosen the best response.0yes but 50% of the time its inf and the other 50% its +inf.. so which one is the right answer?

anonymous

Best ResponseYou've already chosen the best response.0nope its not infinity, when u differentiate for the fourth, fifth, sixth and so on u wud only get +infinity apart from the 3 differentiation
